3.6.18: Security fixes

Packages have been updated to the latest security versions.
An authorization/sensitive information disclosure vulnerability was identified in GitHub Enterprise Server that allowed a fork to retain read access to an upstream repository after the fork’s visibility was changed to private. This vulnerability was reported via the GitHub Bug Bounty Program and assigned CVE-2023-23763. [Updated: 2023-09-01]

3.6.18: Bug fixes

If MinIO was configured for external blob storage on an instance with GitHub Actions enabled and MinIO was configured for bucket replication, the instance’s credential validation with MinIO would occasionally fail.
syslog-ng configurations for containerized services caused errors for log forwarding services. The configurations have been removed.
When an instance exhausted available memory, in some cases, the system’s out-of-memory killer (OOMK) killed the process for dockerd, causing Nomad to fail to recover after systemd restarted Docker.
When an administrator used GitHub Enterprise Importer on versions 3.7 and below to migrate repositories from GitHub Enterprise Server, the system backup size would increase after running many migrations due to storage files not being cleaned up.
On an instance with Dependabot alerts enabled, repository creation could fail if an organization owner did not set a primary email address.

3.6.18: Changes

Administrators with SSH access to an instance can view the version of GitHub Enterprise Server on the instance by using the -v flag with the ghe-version utility.
As a security measure, GitHub Pages does not build sites that contain symbolic links except when using custom GitHub Actions workflows. When the page builder encounters a symbolic link, the build will fail with an error indicating that the symbolic link should be dereferenced. Custom workflows for GitHub Pages are available in GitHub Enterprise Server 3.7 and later.

3.6.18: Known issues

Custom firewall rules are removed during the upgrade process.
Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
In a repository’s settings, enabling the option to allow users with read access to create discussions does not enable this functionality.
Custom patterns for secret scanning have .* as an end delimiter, specifically in the “After secret” field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository’s history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.
Following an upgrade to GitHub Enterprise Server 3.6 or later, existing inconsistencies in a repository such as broken refs or missing objects, may now be reported as errors like invalid sha1 pointer 0000000000000000000000000000000000000000, Zero-length loose reference file, or Zero-length loose object file. Previously, these indicators of repository corruption may have been silently ignored. GitHub Enterprise Server now uses an updated Git version with more diligent error reporting enabled. For more information, see this upstream commit in the Git project.

If you suspect a problem like this exists in one of your repositories, contact GitHub Enterprise Support for assistance.
On an instance in a high-availability configuration, passive replica nodes accept Git client requests and forward the requests to the primary node.
If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.
When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

GitHub Actions (actions) and Microsoft SQL (mssql) did not appear in the list of processes within the instances monitor dashboard.
After an administrator used the /setup/api/start REST API endpoint to upload a license, the configuration run failed with a Connection refused error during the migrations phase.
In some cases, on an instance with a GitHub Advanced Security license and secret scanning enabled, users may have seen a discrepancy between the number of alerts displayed on a repositorys “Security” tab and in the sidebar for the “Security” tab.
On an instance in a cluster configuration, when a site administrator set maintenance mode using ghe-maintenance -s, a Permission denied error appeared when the utility tried to access /data/user/common/cluster.conf.
On an instance in a high availability configuration, if an administrator tore down replication from a replica node using ghe-repl-teardown immediately after running ghe-repl-setup, but before ghe-repl-start, an error indicated that the script cannot launch /usr/local/bin/ghe-single-config-apply - run is locked. ghe-repl-teardown now displays an informational alert and continues the teardown.
During configuration of high availability, if a site administrator interrupted the ghe-repl-start utility, the utility erroneously reported that replication was configured, and the instance would not perform expected clean-up operations.
Responses from the /repositories REST API endpoint erroneously included deleted repositories.
When a site administrator used ghe-migrator to migrate data to GitHub Enterprise Server, in some cases, nested team relationships would not persist after teams were imported.
If a repository contained a CODEOWNERS file with check annotations, pull requests “Files changed” tab returned a 500 error and displayed “Oops, something went wrong” in the “Unchanged files with check annotations” section.
After upgrading an instance with a GitHub Advanced Security license to GitHub Enterprise Server 3.6 or 3.7, creating a repository or viewing the security settings page for an organization or repository could result in a 500 error due to a GitHub Advanced Security backfill job not completing before the upgrade started.
On an instance with GitHub Actions enabled, if a user manually triggered a workflow using the REST API but did not specify values for optional booleans, the API failed to validate the request and returned a 422 error.
The CSV reports for all users and all active users, available from the site admin dashboard, did not consider recent access using SSH or personal access tokens.
On an instance with GitHub Connect enabled, if “Users can search GitHub.com” was enabled, users would not see issues in private and internal repositories in search results for GitHub.com.
GitHub Enterprise Server published distribution metrics that cannot be processed by collectd. The metrics included pre_receive.lfsintegrity.dist.referenced_oids, pre_receive.lfsintegrity.dist.unknown_oids, and git.hooks.runtime.
On an instance with a GitHub Advanced Security license, if code scanning had been used while running GitHub Enterprise Server 3.4 or earlier, a subsequent upgrade from 3.5 to 3.6 or 3.7 could fail when attempting to add a unique index to a database table.
On an instance with GitHub Packages enabled, after users pushed to the Container registry, the instance erroneously responded with a 429 Too Many Requests error in cases when the instance could accommodate the request. The limits have been raised, and users should receive this message less often. [Updated: 2023-05-30]

3.6.11: Changes

After an enterprise owner enables Dependabot updates, the instance creates the initial set of updates faster.
On an instance in a cluster configuration, when a site administrator sets maintenance mode on a single cluster node using ghe-maintenance -s, the utility warns the administrator to use ghe-cluster-maintenance -s to set maintenance mode on all of the clusters nodes. For more information, see “Enabling and scheduling maintenance mode.”
When a site administrator configures an outbound web proxy server for GitHub Enterprise Server, the instance now validates top-level domains (TLDs) excluded from the proxy configuration. By default, you can exclude public TLDs that the IANA specifies. Site administrators can specify a list of unregistered TLDs to exclude using ghe-config. The . prefix is required for any public TLDs. For example, .example.com is valid, but example.com is invalid. For more information, see “Configuring an outbound web proxy server.”
To avoid intermittent issues with the success of Git operations on an instance with multiple nodes, GitHub Enterprise Server checks the status of the MySQL container before attempting a SQL query. The timeout duration has also been reduced.
The default path for output from ghe-saml-mapping-csv -d is /data/user/tmp instead of /tmp. For more information, see “Command-line utilities.”
Releases in the 3.6 series of GitHub Enterprise Server are no longer suitable for testing SCIM. To continue using the private beta of SCIM, upgrade your instance to version 3.7.3 or later. For more information, see “Upgrading GitHub Enterprise Server.” [Updated: 2023-04-17]

3.6.11: Known issues

On a freshly set up GitHub Enterprise Server instance without any users, an attacker could create the first admin user.
Custom firewall rules are removed during the upgrade process.
Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
Instances experiencing a high sustained number of concurrent Git requests may experience performance issues. If you suspect that this issue is affecting your instance, contact GitHub Support. For more information, see “Creating a support ticket.” [Updated: 2022-12-07]
In a repository’s settings, enabling the option to allow users with read access to create discussions does not enable this functionality.
Custom patterns for secret scanning have .* as an end delimiter, specifically in the “After secret” field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository’s history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.
Following an upgrade to GitHub Enterprise Server 3.6 or later, existing inconsistencies in a repository such as broken refs or missing objects, may now be reported as errors like invalid sha1 pointer 0000000000000000000000000000000000000000, Zero-length loose reference file, or Zero-length loose object file. Previously, these indicators of repository corruption may have been silently ignored. GitHub Enterprise Server now uses an updated Git version with more diligent error reporting enabled. For more information, see this upstream commit in the Git project.

If you suspect a problem like this exists in one of your repositories, contact GitHub Enterprise Support for assistance.
An upgrade to GitHub Enterprise Server 3.6 or 3.7 from 3.5 or earlier may be long running if a large number of deleted repositories exist. Deleted repositories are purged automatically after 90 days, but for a faster upgrade they can be purged manually. If you suspect you have thousands of recently deleted repositories, and you are concerned about a long running upgrade, contact GitHub Enterprise Support for assistance purging deleted repositories. [Updated: 2023-05-09]
On an instance configured for SAML authentication, when signing in, users may erroneously see an error indicating “User has already been taken.” [Updated: 2023-07-18]
In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support. [Updated: 2023-08-24]

December 13, 2022

📣 This is not the latest patch release of this release series, and this is not the latest release of Enterprise Server. Please use the latest release for the latest security, performance, and bug fixes.

3.6.5: Security fixes

HIGH: A path traversal vulnerability was identified in GitHub Enterprise Server that allowed remote code execution when building a GitHub Pages site. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the instance. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2022-46256.
HIGH: An incorrect authorization vulnerability allowed a scoped user-to-server token to escalate to full admin access for a repository. An attacker would require an account with admin access to install a malicious GitHub App. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.7.0. This vulnerability was reported via the GitHub Bug Bounty program and has been assigned CVE-2022-23741.
MEDIUM: An information disclosure vulnerability was identified in GitHub Enterprise Server that allowed private repositories to be added to a GitHub Actions runner group via the API by a user who did not have access to those repositories, resulting in the repository names being shown in the UI. To exploit this vulnerability, an attacker would need access to the GHES instance, permissions to modify GitHub Actions runner groups, and successfully guess the obfuscated ID of private repositories. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2022-46257.

3.6.5: Bug fixes

A race condition blocked upgrades to GitHub Enterprise Server 3.6 or later until a site administrator retried the upgrade.
Site administrators were not able to manage security products settings for repositories they had unlocked.
When a site administrator ran the ghe-repl-status command on a cache replica via the administrative shell (SSH), the command incorrectly reported overall Git and Alambic cluster replication status information as if it pertained only to cache replication.
When a site administrator ran the ghe-repl-sync-ca-certificates command from an instances primary node via the administrative shell (SSH), the command only replicated CA certificates from the instances primary node to a single replica node. The command did not replicate the certificates to all available replica nodes.
When using repository caching with an instance in a high availability configuration, if a Git client used SSH instead of HTTPS for a repositorys remote URL, Git LFS would fetch objects from the instances primary node instead of the appropriate cache replica node.
Installation of GitHub Enterprise Server on the VMware ESXi hypervisor failed due to the generation of an OVA file with an invalid capacity value.
When users performed an operation using the API, GitHub Enterprise Server enforced repository size quotas even when disabled globally.
If a user uploaded more than one file while creating a new Gist, the user could not delete any files uploaded after the first.
In some cases, searches via the API returned a 500 error.
In some cases, when browsing repositories in the web interface, an erroneous banner indicated that a repository didn’t contain a specific undefined path on the current branch.
The member webhook event did not include the from and to field values for the permission field as part of the changes field.
Adding a collaborator to a user-owned fork of a private, organization-owned repository with triage, maintain, or custom access resulted in a 500 error.
In some cases, the page for setting up code scanning would erroneously report that GitHub Actions was not configured for the instance.
After a user’s account was deleted from the instance, image attachments that the user uploaded in comments were no longer visible in the web interface.
A debug-level message appeared in a system log, which could consume space rapidly on the instance’s root storage volume.

3.6.5: Changes

To avoid failing domain verification due to the 63-character limit enforced by DNS providers for DNS records, the GitHub-generated TXT record to verify domain ownership is now limited to 63 characters.
After an enterprise owner enables Dependabot alerts, GitHub Enterprise Server enqueues the synchronization of advisory data to ensure hourly updates from GitHub.com.
A user’s list of recently accessed repositories no longer includes deleted repositories.
Releases in the 3.6 series of GitHub Enterprise Server are no longer suitable for testing SCIM. To continue using the private beta of SCIM, upgrade your instance to version 3.7.3 or later. For more information, see “Upgrading GitHub Enterprise Server.” [Updated: 2023-04-17]

3.6.5: Known issues

On a freshly set up GitHub Enterprise Server instance without any users, an attacker could create the first admin user.
Custom firewall rules are removed during the upgrade process.
Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
When “Users can search GitHub.com” is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.
The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
Resource limits that are specific to processing pre-receive hooks may cause some pre-receive hooks to fail.
Actions services need to be restarted after restoring an instance from a backup taken on a different host.
In a repository’s settings, enabling the option to allow users with read access to create discussions does not enable this functionality.
In some cases, users cannot convert existing issues to discussions.
Custom patterns for secret scanning have .* as an end delimiter, specifically in the “After secret” field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository’s history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.
Following an upgrade to GitHub Enterprise Server 3.6 or later, existing inconsistencies in a repository such as broken refs or missing objects, may now be reported as errors like invalid sha1 pointer 0000000000000000000000000000000000000000, Zero-length loose reference file, or Zero-length loose object file.

MEDIUM: Pull request preview links did not properly sanitize URLs, allowing a malicious user to embed dangerous links in the instances web UI. This vulnerability was reported via the GitHub Bug Bounty program.
MEDIUM: An incorrect authorization vulnerability was identified in GitHub Enterprise Server that allowed a repository-scoped token with read/write access to modify GitHub Actions workflow files without a workflow scope. The “Repository contents” should enforce workflow scope. This vulnerability was reported via the GitHub Bug Bounty program and has been assigned CVE-2022-46258.

3.6.4: Bug fixes

If a GitHub Actions dependency uses a pinned SHA version, Dependabot will no longer mark the dependency as vulnerable.
Setting the maintenance mode with an IP Exception List would not persist across upgrades.
GitHub Pages builds could time out on instances in AWS that are configured for high availability.
Status details for the replication of Git LFS objects to repository cache replica nodes were not visible in the ghe-repl-status output on those nodes.
After configuration of Dependabot and alert digest emails, the instance would send digest emails to suspended users.
The audit log timestamp for Dependabot alert events returned the creation date of the alert instead of the timestamp when a user took action on the alert.
When using the CodeQL action, the runs annotations would include a spurious HttpError: Upload not found error.
When accessing an instances JavaScript resources from behind a proxy, the browser displayed Cross-Origin Resource Sharing (CORS) errors.
If a user named a status check with leading or trailing spaces, the instance created a duplicate check if another check existed with the same name and no leading or trailing spaces.
If a user configured a pre-receive hook for multiple repositories, the instances Hooks page would not always display the correct status for the hook.
In some cases, an instance could replace an active repository with a deleted repository.
Git LFS objects in a repository with a cache replication policy would not be copied to cache replicas if the total number of objects in the repository exceeded 5,000.
After running migrations for the GitHub Enterprise Importer on an instance configured for high availability, replication of migration storage assets would not catch up.
Zombie processes no longer accumulate in the gitrpcd container.

3.6.4: Changes

If a site administrator has not yet configured GitHub Actions for the instance, the UI for setting up code scanning will prompt the user to configure GitHub Actions.

📣 This is not the latest patch release of this release series, and this is not the latest release of Enterprise Server. Please use the latest release for the latest security, performance, and bug fixes.

3.6.1: Bug fixes

After unlocking a repository for temporary access, a site administrator was unable to manage settings for security products in the repository.
Duplicate administrative SSH keys could appear in both the Management Console and the /home/admin/.ssh/authorized_keys file.
The site admin page for individual users at http(s)://HOSTNAME/stafftools/users/USERNAME/admin contained functionality not intended for GitHub Enterprise Server.
In some cases, running ghe-cluster-config-apply could replicate an empty configuration to existing nodes in a cluster.
In some cases, configuration runs started with ghe-config-apply did not complete, or returned a Container count mismatch error.
After updating a self-signed TLS certificate on a GitHub Enterprise Server instance, UI elements on some pages in the web interface did not appear.
In some cases, background tasks could stall due to a library that was used concurrently despite not being thread-safe.
The site admin bar at the top of the web interface contained a broken link to the SHA for the currently running version of the application.
Organization owners were unable to set the level of access required to create discussions.
Discussions users were incorrectly directed to the community guidelines for GitHub.com.
In some cases, users were incorrectly instructed to verify their email before creating a discussion.
Alerts from secret scanning for GitHub Advanced Security customers were missing in the web UI and REST API if a site administrator did not upgrade directly to GitHub Enterprise Server 3.4. The alerts are now visible.

3.6.1: Changes

Generation of support bundles is faster as a result of parallelized log sanitization. For more information about support bundles, see “Providing data to GitHub Support.”
APIs that contain the organization or org route now accept either the organization’s slug or ID. Previously, the APIs only accepted slugs, which caused Link headers for GitHub Advanced Security endpoints to be inaccessible. For more information, see “Organizations” in the REST API documentation.

When “Users can search GitHub.com” is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.
The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
Resource limits that are specific to processing pre-receive hooks may cause some pre-receive hooks to fail.
Actions services need to be restarted after restoring an instance from a backup taken on a different host.
In a repository’s settings, enabling the option to allow users with read access to create discussions does not enable this functionality.
In some cases, users cannot convert existing issues to discussions.
Custom patterns for secret scanning have .* as an end delimiter, specifically in the “After secret” field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository’s history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.
After upgrading a replica node to GitHub Enterprise Server 3.6.0 or later and restarting replication, in some situations Git replication may stop progressing and continue to show WARNING: git replication is behind the primary …. If you encounter this known issue contact GitHub Support. For more information, see “Creating a support ticket.” [Updated: 2022-10-03]
GitHub Pages builds may time out on instances in AWS that are configured for high availability. [Updated: 2022-11-28]

On an instance configured for SAML authentication, when signing in, users may erroneously see an error indicating “User has already been taken.” [Updated: 2023-07-18]
In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support. [Updated: 2023-08-24]

Enterprise Server 3.6.0Download GitHub Enterprise Server 3.6.0

August 16, 2022

📣 This is not the latest patch release of this release series, and this is not the latest release of Enterprise Server. Please use the latest release for the latest security, performance, and bug fixes.

Note: If your GitHub Enterprise Server instance is running a release candidate build, you can’t upgrade with a hotpatch. We recommend that you only run release candidates in a test environment.

For upgrade instructions, see “Upgrading GitHub Enterprise Server.”

3.6.0: Features

Infrastructure
- Repository caching is generally available. Repository caching increases Git read performance for distributed developers, providing the data locality and convenience of geo-replication without impact on push workflows. With the general availability release, GitHub Enterprise Server caches both Git and Git LFS data. For more information, see “About repository caching.”
Instance security
- Site administrators can configure a cutoff date for allowing Git operations over SSH that use an RSA key and are signed by the SHA-1 hash function. By default, these connections will fail for RSA keys added to user accounts after the cutoff date of midnight UTC on August 1, 2022. For more information, see Deprecations. [Updated: 2023-01-31]
- GitHub Enterprise Server optionally allows the advertisement of an Ed25519 host key. For more information, see “Configuring host keys for your instance.”
- You can require TLS encryption for incoming SMTP connections to your instance. For more information, see “Configuring email for notifications.”
  - Note: This feature is unavailable in GitHub Enterprise Server 3.6.0 and 3.6.1. The feature is available in the 3.6.2 release. [Updated: 2022-09-22]
Audit logs
- You can stream audit log and Git events for your instance to Amazon S3, Azure Blob Storage, Azure Event Hubs, Google Cloud Storage, or Splunk. Audit log streaming is in public beta and subject to change. For more information, see “Streaming the audit log for your enterprise.”
GitHub Connect
- Server Statistics is now generally available. Server Statistics collects aggregate usage data from your GitHub Enterprise Server instance, which you can use to better anticipate the needs of your organization, understand how your team works, and show the value you get from GitHub Enterprise Server. For more information, see “About Server Statistics.”
Administrator experience
- Enterprise owners can join organizations on the instance as a member or owner from the enterprise account’s Organizations page. For more information, see “Managing your role in an organization owned by your enterprise.”
- Enterprise owners can allow users to dismiss the configured global announcement banner. For more information, see “Customizing user messages for your enterprise.”
GitHub Advanced Security
- Users on an instance with a GitHub Advanced Security license can opt to receive a webhook event that triggers when an organization owner or repository administrator enables or disables a code security or analysis feature. For more information, see the following documentation.
  - “Webhook events and payloads” in the webhook documentation
  - “Managing security and analysis settings for your organization”
  - “Managing security and analysis features for your repository”
- Users on an instance with a GitHub Advanced Security license can optionally add a comment when dismissing a code scanning alert in the web UI or via the REST API. Dismissal comments appear in the event timeline. Users can also add or retrieve a dismissal comment via the REST API. For more information, see “Triaging code scanning alerts in pull requests” and “Code Scanning” in the REST API documentation.
- On instances with a GitHub Advanced Security license, secret scanning prevents the leak of secrets in the web editor. For more information, see “Protecting pushes with secret scanning.”
- Enterprise owners and users on an instance with a GitHub Advanced Security license can view secret scanning alerts and bypasses of secret scanning’s push protection in the enterprise and organization audit logs, and via the REST API. For more information, see the following documentation.
  - “Protecting pushes with secret scanning”
  - “Audit log events for your enterprise”
  - “Reviewing the audit log for your organization”
  - “Secret Scanning” in the REST API documentation
- Enterprise owners on an instance with a GitHub Advanced Security license can perform dry runs of custom secret scanning patterns for the enterprise, and all users can perform dry runs when editing a pattern. Dry runs allow you to understand a pattern’s impact across the entire instance and hone the pattern before publication and generation of alerts. For more information, see “Defining custom patterns for secret scanning.”
- Users on an instance with a GitHub Advanced Security license can use sort and direction parameters in the REST API when retrieving secret scanning alerts, and sort based on the alert’s created or updated fields. The new parameters are available for the entire instance, or for individual organizations or repositories. For more information, see the following documentation.
  - “List secret scanning alerts for an enterprise”
  - “List secret scanning alerts for an organization”
  - “List secret scanning alerts for a repository”
  - “Secret Scanning” in the REST API documentation
- The contents of the github/codeql-go repository have moved to the github/codeql repository, to live alongside similar libraries for all other programming languages supported by CodeQL. The open-source CodeQL queries, libraries, and extractor for analyzing codebases written in the Go programming language with GitHub’s CodeQL code analysis tools can now be found in the new location. For more information, including guidance on migrating your existing workflows, see github/codeql-go#741.
Dependabot
- Enterprise owners on instances with a GitHub Advanced Security license can see an overview of Dependabot alerts for the entire instance, including a repository-centric view of application security risks, and an alert-centric view of all secret scanning and Dependabot alerts. The views are in beta and subject to change, and alert-centric views for code scanning are planned for a future release of GitHub Enterprise Server. For more information, see “Viewing the security overview.”
- Users can select multiple Dependabot alerts, then dismiss or reopen or dismiss the alerts. For example, from the Closed alerts tab, you can select multiple alerts that have been previously dismissed, and then reopen them all at once. For more information, see “About Dependabot alerts.”
  - Note: This feature is unavailable in GitHub Enterprise Server 3.6.0. The feature is available in GitHub Enterprise Server 3.7.0 and later. [Updated: 2022-10-19]
- Dependabot updates @types dependencies alongside corresponding packages in TypeScript projects. Before this change, users would see separate pull requests for a package and the corresponding @types package. This feature is automatically enabled for repositories containing @types packages in the project’s devDependencies within the package.json file. You can disable this behavior by setting the ignore field in your dependabot.yml file to @types/*. For more information, see “About Dependabot version updates” and “Configuration options for the dependabot.yml file.”
Code security
- GitHub Actions can enforce dependency reviews on users’ pull requests by scanning for dependencies, and will warn users about associated security vulnerabilities. The dependency-review-action action is supported by a new API endpoint that diffs the dependencies between any two revisions. For more information, see “About dependency review.”
- The dependency graph detects Cargo.toml and Cargo.lock files for Rust. These files will be displayed in the Dependency graph section of the Insights tab. Users will receive Dependabot alerts and updates for vulnerabilities associated with their Rust dependencies. Package metadata, including mapping packages to repositories, will be added at a later date. For more information, see “About the dependency graph.”
- If GitHub Connect is enabled for your instance, users can contribute an improvement to a security advisory in the GitHub Advisory Database. To contribute, click Suggest improvements for this vulnerability while viewing an advisory’s details. For more information, see the following articles.
  - “Managing GitHub Connect”
  - “Browsing security vulnerabilities in the GitHub Advisory Database” in the GitHub Enterprise Cloud documentation
  - “About GitHub Security Advisories for repositories” in the GitHub Enterprise Cloud documentation
  - “Editing security advisories in the GitHub Advisory Database” in the GitHub Enterprise Cloud documentation
GitHub Actions
- Within a workflow that calls a reusable workflow, users can pass the secrets to the reusable workflow with secrets: inherit. For more information, see “Reusing workflows.”
- When using GitHub Actions, to reduce the risk of merging a change that was not reviewed by another person into a protected branch, enterprise owners and repository administrators can prevent Actions from creating pull requests. Organization owners could previously enable this restriction. For more information, see the following articles.
  - “Enforcing policies for GitHub Actions in your enterprise”
  - “Disabling or limiting GitHub Actions for your organization”
  - “Managing GitHub Actions settings for a repository”
- Users can write a single workflow triggered by workflow_dispatch and workflow_call, and use the inputs context to access input values. Previously, workflow_dispatch inputs were in the event payload, which increased difficulty for workflow authors who wanted to write one workflow that was both reusable and manually triggered. For workflows triggered by workflow_dispatch, inputs are still available in the github.event.inputs context to maintain compatibility. For more information, see “Contexts.”
- To summarize the result of a job, users can generate Markdown and publish the contents as a job summary. For example, after running tests with GitHub Actions, a summary can provide an overview of passed, failed, or skipped tests, potentially reducing the need to review the full log output. For more information, see “Workflow commands for GitHub Actions.”
- To more easily diagnose job execution failures during a workflow re-run, users can enable debug logging, which outputs information about a job’s execution and environment. For more information, see “Re-running workflows and jobs” and “Using workflow run logs.”
- If you manage self-hosted runners for GitHub Actions, you can ensure a consistent state on the runner itself before and after a workflow run by defining scripts to execute. By using scripts, you no longer need to require that users manually incorporate these steps into workflows. Pre- and post-job scripts are in beta and subject to change. For more information, see “Running scripts before or after a job.”
GitHub Packages
- Enterprise owners can migrate container images from the GitHub Docker registry to the GitHub Container registry. The Container registry provides the following benefits.
  - Improves the sharing of containers within an organization
  - Allows the application of granular access permissions
  - Permits the anonymous sharing of public container images
  - Implements OCI standards for hosting Docker images
  The Container registry is in beta and subject to change. For more information, see “Migrating your enterprise to the Container registry from the Docker registry.”
- GitHub Discussions is available for GitHub Enterprise Server. GitHub Discussions provides a central gathering space to ask questions, share ideas, and build connections. For more information, see “GitHub Discussions.”
- Enterprise owners can configure a policy to control whether people’s usernames or full names are displayed within internal or public repositories. For more information, see “Enforcing repository management policies in your enterprise.”
Organizations
- Users can create member-only READMEs for an organization. For more information, see “Customizing your organization’s profile.”
- Organization owners can pin a repository to an organization’s profile directly from the repository via the new Pin repository dropdown. Pinned public repositories appear to all users of your instance, while public, private, and internal repositories are only visible to organization members.
Repositories
- While creating a fork, users can customize the fork’s name. For more information, see “Fork a repo.”
- Users can delete a branch that’s associated with an open pull request. For more information, see “Creating and deleting branches within your repository.”
- Repositories with multiple licenses display all of the licenses in the “About” sidebar on the Code tab. For more information, see “Licensing a repository.”
- Users can require a successful deployment of a branch before anyone can merge the pull request associated with the branch. For more information, see “About protected branches” and “Managing a branch protection rule.”
- Enterprise owners can prevent organization owners from inviting collaborators to repositories on the instance. For more information, see “Enforcing a policy for inviting collaborators to repositories.”
- Users can grant exceptions to GitHub Apps for any branch protection rule that supports exceptions. For more information, see “About apps” and “Managing a branch protection rule.”
Commits
- For public GPG signing keys that are expired or revoked, GitHub Enterprise Server verifies Git commit signatures and show commits as verified if the user made the commit while the key was still valid. Users can also upload expired or revoked GPG keys. For more information, see “About commit signature verification.”
- To affirm that a commit complies with the rules and licensing governing a repository, organization owners and repository administrators can now require developers to sign off on commits made through the web interface. For more information, see “Managing the commit signoff policy for your organization” and “Managing the commit signoff policy for your repository.”
Pull requests
- Using the file tree located in the Files changed tab of a pull request, users can navigate modified files, understand the size and scope of changes, and focus reviews. The file tree appears if a pull request modifies at least two files, and the browser window is sufficiently wide. For more information, see “Reviewing proposed changes in a pull request” and “Filtering files in a pull request.”
- Users can default to using pull requests titles as the commit message for all squash merges. For more information, see “Configuring commit squashing for pull requests.”
GitHub Mobile
- In GitHub Mobile for iOS 1.80.0 and later, users can edit files within a pull request’s topic branch. Support for editing files will come to GitHub Mobile for Android in a future release. [Updated: 2022-09-13]
Releases
- When viewing the details for a particular release, users can see the creation date for each release asset. For more information, see “Viewing your repository’s releases and tags.”
- While creating a release with automatically generated release notes, users can see the tag identified as the previous release, then choose to select a different tag to specify as the previous release. For more information, see “Automatically generated release notes.”
Markdown
- Editing Markdown in the web interface has been improved.
  - After a user selects text and pastes a URL, the selected text will become a Markdown link to the pasted URL.
  - When a user pastes spreadsheet cells or HTML tables, the resulting text will render as a table.
  - When a user copies text containing links, the pasted text will include the link as a Markdown link.
  For more information, see “Basic writing and formatting syntax.”
- When editing a Markdown file in the web interface, clicking the Preview tab will automatically scroll to the place in the preview that you were editing. The scroll location is based on the position of your cursor before you clicked the Preview tab.

3.6.0: Changes

The unencrypted and unauthenticated Git protocol is now disabled by default. If you do not re-enable the protocol after you upgrade to GitHub Enterprise Server 3.6 or later, git:// connections on port 9418 will return the following error.
```
The unauthenticated git protocol on port 9418 is no longer supported.
```
If you wish to support the protocol in your environment, you must manually re-enable the feature. For more information, see “Enforcing repository management policies in your enterprise” and the GitHub Blog. [Updated: 2023-01-31]
Interactive elements in the web interface such as links and buttons show a visible outline when focused with a keyboard, to help users find the current position on a page. In addition, when focused, form fields have a higher contrast outline.
If a user refreshes the page while creating a new issue or pull request, the assignees, reviewers, labels and projects will all be preserved.
VMware vSphere ESXi hypervisor version 7.0 is now supported. [Updated: 2022-09-07]
Releases in the 3.6 series of GitHub Enterprise Server are no longer suitable for testing SCIM. To continue using the private beta of SCIM, upgrade your instance to version 3.7.3 or later. For more information, see “Upgrading GitHub Enterprise Server.” [Updated: 2023-04-17]

3.6.0: Known issues

On a freshly set up GitHub Enterprise Server instance without any users, an attacker could create the first admin user.
Custom firewall rules are removed during the upgrade process.
Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
When “Users can search GitHub.com” is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.
The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.
Resource limits that are specific to processing pre-receive hooks may cause some pre-receive hooks to fail.
Actions services need to be restarted after restoring an instance from a backup taken on a different host.
In a repository’s settings, enabling the option to allow users with read access to create discussions does not enable this functionality.
In some cases, users cannot convert existing issues to discussions.
Custom patterns for secret scanning have .* as an end delimiter, specifically in the “After secret” field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository’s history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.
In some cases, GitHub Advanced Security customers who upgrade to GitHub Enterprise Server 3.6 may notice that alerts from secret scanning are missing in the web UI and REST API. To ensure the alerts remain visible, do not skip 3.4 as you upgrade to the latest release. To plan an upgrade through 3.4, see the Upgrade assistant.
- To display the missing alerts for all repositories owned by an organization, organization owners can navigate to the organization’s Code security and analysis settings, then click Enable all for secret scanning. For more information, see “Managing security and analysis settings for your organization.”
- To display the missing alerts for an individual repository, people with admin access to the repository can disable then enable secret scanning for the repository. For more information, see “Managing security and analysis settings for your repository.”
A fix is available in the 3.6.1 patch release. [Updated: 2022-09-01]
After upgrading a replica node to GitHub Enterprise Server 3.6.0 or later and restarting replication, Git replication may stop progressing and continue to show WARNING: git replication is behind the primary ….

CVE-2022-39209: Unbounded resource exhaustion may lead to denial of service

cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior to 0.29.0.gfm.6 a polynomial time complexity issue in cmark-gfm's autolink extension may lead to unbounded resource exhaustion and subsequent denial of service. Users may verify the patch by running `python3 -c 'print("![l"* 100000 + "\n")' | ./cmark-gfm -e autolink`, which will resource exhaust on unpatched cmark-gfm but render correctly on patched cmark-gfm. This vulnerability has been patched in 0.29.0.gfm.6. Users are advised to upgrade. Users unable to upgrade should disable the use of the autolink extension.

CVE-2021-32762: Integer overflow that can lead to heap overflow in redis-cli, redis-sentinel on some platforms

Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks. Most modern systems do and are therefore not likely to be affected. Furthermore, by default redis-sentinel uses the jemalloc allocator which is also not vulnerable. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.
