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

Warning: A change to MySQL in GitHub Enterprise Server 3.9 and later may impact the performance of your instance. Before you upgrade, make sure you’ve read the “Known issues” section of these release notes.

3.9.6: Security fixes

HIGH: Due to an incorrect permission assignment for some configuration files, an attacker with access to a local operating system user account could read MySQL connection details including the MySQL password. GitHub has requested CVE ID CVE-2023-23767 for this vulnerability.
Packages have been updated to the latest security versions.

3.9.6: Bug fixes

The ghe-cluster-repl-status command did not display all replication statuses.
On an instance in a cluster configuration with high availability enabled, ghe-config-apply timed out while waiting for hookshot-go to start on replica application nodes.
SpokesRepairRepoReplicaJob and SpokesSyncCacheReplicaJob jobs failed, causing cache server replicas to not update and potentially prolonging replication issues.
/var/log/lastlog was not copied over as a sparse file during ghe-upgrade, which could cause issues by using additional disk space.
On an instance in a cluster configuration, when managing maintenance mode using ghe-cluster-maintenance, an erroneous warning appeared that read "Warning: Maintenance mode set on primary, please make sure to set it on any active replica if needed". - | ghe-repl-status did not identify Git replicas in certain incomplete states and incorrectly suggested that a failover could be performed safely. In some cases, this led to data loss during failover.
Repository exports using ghe-migrator or the REST API’s operation for organization migrations could fail when a large number of commit comments or long commit comments were present.
On an instance with a GitHub Advanced Security license and secret scanning enabled, secret scanning suggested incorrect filters when viewing both open and closed alerts.
On instances using the private beta of SCIM provisioning, some users were presented with a “single sign-in” hover card.
On an instance with multiple nodes, ghe-spokes status did not identify Git replicas in certain incomplete states, causing a false report that replication was in sync and leading to data loss or replication issues during failover.
On an instance with GitHub Actions enabled, administrators received a 500 error after attempting to force cancel a workflow run via Staff Tools.
On an instance with a GitHub Advanced Security license, repositories within organizations created using the + dropdown menu did not have GitHub Advanced Security features enabled automatically, even if the features should have been enabled.
As a security measure, GitHub Pages does not build sites that contain symbolic links except when using custom GitHub Actions workflows. This change strengthens GitHub Pages’s symbolic link detection.
On an instance with a GitHub Advanced Security license and secret scanning enabled, dry runs sometimes incorrectly reported no results for custom patterns.

3.9.6: Changes

Instructions in the “Migrations” section of the Management Console clarify that only standard AWS S3 endpoints are supported when configuring AWS S3 as a blob storage provider for migrations.
When running async repository repairs, the output message about scheduling a repair job is more accurate.
On an instance in a cluster configuration, administrators can identify the repository networks or gists that are common across a specified set of storage nodes using the spokesctl find-on-replicas command.

3.9.6: Known issues

Custom firewall rules are removed during the upgrade process.
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.
During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.
If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see “Troubleshooting access to the Management Console.”
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.
The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn’t required, and outputs an error instead of a warning.
On an instance with subdomain isolation disabled, Mermaid diagrams in the web UI display an “Unable to render rich display” error and fail to render.
When enabling CodeQL via default setup at scale, some checks related to GitHub Actions are omitted, potentially preventing the process from completing.
After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see “Known issues with upgrades to your instance.” [Updated: 2023-08-11]
After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance’s performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see “Known issues with upgrades to your instance.”
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.
On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes.
Jobs in a deprecated queue are not processed and may accumulate over time. These jobs are reflected in the monitor dashboard’s “Aqueduct queue depth” graph as an increase in resource_activity. In some cases, a buildup of unprocessed jobs can result in memory exhaustion. If you observe memory exhaustion on your instance and see a high metric for resource_activity, contact GitHub Support.
When an administrator uses the -p flag with the ghe-support-bundle utility to collect data for a specific number of hours, the utility erroneously collects more logs than necessary.

3.9.2: Changes

Added a pre-upgrade check to validate the GHES version and MySQL configuration before allowing an upgrade to 3.9.
Adjusted the timeout threshold for shutting down MySQL to prevent premature termination when upgrading to GHES 3.9.

3.9.2: Known issues

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9, I/O utilization will increase, and in some cases the instance’s performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see “Known issues with upgrades to your instance.”
After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see “Known issues with upgrades to your instance.” [Updated: 2023-08-11]
The Management Console may get stuck in a loop showing “Checking requirements…” when attempting to download an update. It is safe to proceed the update process manually via the command line.
When enabling CodeQL via default setup at scale, some checks related to GitHub Actions are omitted, potentially preventing the process from completing.
After restoration of a backup created using GitHub Enterprise Server Backup Utilities 3.7.0, 3.8.0, or 3.9.0, users may not be able to sign into the instance. To fix this issue, plus a bug that was preventing secret scanning encryption keys from being backed up, upgrade your backup host to use GitHub Enterprise Server Backup Utilities 3.9.1 and generate a new full backup using ghe-backup. For more information on using an existing backup, see “Known issues with backups for your instance.” [Updated: 2023-07-31]
On an instance in a cluster configuration, after you upgrade nodes other than the primary MySQL node and before you upgrade the primary MySQL node, the following output may appear multiple times after you run ghe-config-apply.
```
Error response from daemon: conflict: unable to delete IMAGE_ID (cannot be forced) - image is being used by running container CONTAINER_ID
```
You can safely ignore this message.

3.9.1: Security fixes

MEDIUM: An attacker with write access to a repository could craft a pull request that would hide commits made in its source branch. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2023-23764. [Updated: 2023-07-26]
An attacker with access to the password hash of the root site administrator user for the instance’s Management Console could make requests to the password API endpoint from outside of the instance.
Packages have been updated to the latest security versions.
LOW: An incorrect comparison vulnerability was identified in GitHub Enterprise Server that allowed commit smuggling by displaying an incorrect diff in a re-opened Pull Request. To exploit this vulnerability, an attacker would need write access to the repository. This vulnerability was reported via the GitHub Bug Bounty Program and was assigned CVE-2023-23765.

3.9.1: 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.
Customers who use Azure Blob store as the remote blob provider to back GitHub Packages would have validation errors if the EndpointSuffix part of their Connection string was anything other than core.windows.net. Now all valid EndpointSuffix are accepted.
When a user viewed a Jupyter notebook, GitHub Enterprise Server returned a 500 error code if the instance was configured with a self-signed TLS certificate.
After creation of a blob object from the web UI, pre-receive hook events were missing from the instance’s audit log.
On an instance with an outbound web proxy server configured, the proxy interfered with internal operations that used nomad alloc exec.
On an instance in a cluster configuration, the ghe-cluster-balance behaved inconsistently when displaying status or managing jobs with more than one task group.
.topojson files would not render correctly, but files that conformed to the TopoJSON spec that used a .geojson extension would render correctly.
On an instance configured for LDAP authentication, if the LDAP server sent an empty string for the sshPublicKey attribute, LDAP user sync would fail.
REST API endpoints for managing GitHub Enterprise Server are now functional. For more information, see “Manage GitHub Enterprise Server” in the REST API documentation.
After creation of a new Management Console user, the Management Console did not display the button to copy the new users invitation.
On an instance with Dependabot enabled, in some situations, Dependabot alerts were not updated when a user pushed to a repository.
In some cases, pull requests with more than 25 rich-diff renderable files required that users toggle the diff type to correctly render the files over the 25-file limit.
In rare circumstances, Git commits signed with SSH keys using the RSA algorithm would incorrectly indicate the signature was invalid.
After a migration using GitHub Enterprise Importer, some repository autolink references were created with an incorrect format.
In some cases on an instance without a GitHub Advanced Security license, Redis exceeded the maximum default memory allocation, causing 500 errors for the instance’s users.

For more information, see “Configuring high availability replication for a cluster.”

3.9.1: Known issues

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance’s performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see “Known issues with upgrades to your instance.”
After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see “Known issues with upgrades to your instance.” [Updated: 2023-08-11]
The Management Console may get stuck in a loop showing “Checking requirements…” when attempting to download an update. It is safe to proceed the update process manually via the command line.
When enabling CodeQL via default setup at scale, some checks related to GitHub Actions are omitted, potentially preventing the process from completing.
After restoration of a backup created using GitHub Enterprise Server Backup Utilities 3.7.0, 3.8.0, or 3.9.0, users may not be able to sign into the instance. To fix this issue, plus a bug that was preventing secret scanning encryption keys from being backed up, upgrade your backup host to use GitHub Enterprise Server Backup Utilities 3.9.1 and generate a new full backup using ghe-backup. For more information on using an existing backup, see “Known issues with backups for your instance.” [Updated: 2023-07-31]
On an instance in a cluster configuration, after you upgrade nodes other than the primary MySQL node and before you upgrade the primary MySQL node, the following output may appear multiple times after you run ghe-config-apply.
```
Error response from daemon: conflict: unable to delete IMAGE_ID (cannot be forced) - image is being used by running container CONTAINER_ID
```
You can safely ignore this message.
Custom firewall rules are removed during the upgrade process.
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.
On an instance in a high-availability configuration, passive replica nodes accept Git client requests and forward the requests to the primary node.
The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn’t required, and outputs an error instead of a warning.
When using an outbound web proxy server, the ghe-btop command may fail in some circumstances with the error "Error querying allocation: Unexpected response code: 401".
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.
During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.
If the root site administrator is locked out of the Management Console after failed login attempts, the account will not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see “Troubleshooting access to the Management Console.”
On an instance with subdomain isolation disabled, Mermaid diagrams in the web UI display an “Unable to render rich display” error and fail to render. [Updated: 2023-08-18]
The “Migrations” section is missing from the Management Console, so it isn’t possible to enable, disable, or reconfigure blob storage credentials for migrations. [Updated: 2023-08-18]
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]
On an instance with GitHub Actions enabled, if shared runner groups are configured for the enterprise, the enterprise security overview page may return a 500 error. You can avoid the issue by trying one of the following workarounds.
- Add a runner scale set to the enterprise runner group shared with the repositories.
- Remove access to the enterprise runner group from the affected repositories or organizations.
[Updated: 2023-09-05]
On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes. [Updated: 2023-09-21]
On an instance with GitHub Actions enabled, ephemeral self-hosted runners do not automatically update to the latest version. Users will need to manually update the runners to the latest version. [Updated: 2023-09-29]
Jobs in a deprecated queue are not processed and may accumulate over time. These jobs are reflected in the monitor dashboard’s “Aqueduct queue depth” graph as an increase in resource_activity. In some cases, a buildup of unprocessed jobs can result in memory exhaustion. If you observe memory exhaustion on your instance and see a high metric for resource_activity, contact GitHub Support. [Updated: 2023-10-10]
When an administrator uses the -p flag with the ghe-support-bundle utility to collect data for a specific number of hours, the utility erroneously collects more logs than necessary. [Updated: 2023-10-13]
The settings for enabling scheduled reminders were added unintentionally to this release. Scheduled reminders are not officially supported. [Updated: 2023-10-17]

- On an instance with GitHub Actions and the dependency graph enabled, as well as automatic access to GitHub.com actions using GitHub Connect, the web interface will suggest submission actions within a repository with supported languages. For more information, see the following documentation.
  - “Using the Dependency submission API”
  - “About GitHub Actions for enterprises”
  - “Enabling automatic access to GitHub.com actions using GitHub Connect”
  For repositories that use a language that has a submission action, when users with write access visit their dependency graph (this page), we will show them a prompt that directs them to the Marketplace to find an action that would help them.
- To improve the security of projects that use npm v9, the dependency graph and Dependabot can parse and update package-lock.json files that specify lockfileVersion: 3. For more information, see “About the dependency graph,” “About Dependabot version updates,” and lockfileVersion in the npm documentation.
- To improve the security of Gradle projects, the dependency graph and Dependabot can parse and update Gradle version catalogs in settings.gradle. For more information, see “About Dependabot version updates” and Sharing dependency versions between projects in the Gradle User Manual.
- To ensure that users receive the most relevant and actionable alerts about dependency updates, repository administrators and organization owners can enable or disable Dependabot alerts for an individual repository or organization. For more information, see “Securing your repository” or “Securing your organization.”
- If people with access to a repository do not interact with Dependabot security updates for over 90 days, Dependabot will pause automated pull request activity. For more information, see “About Dependabot security updates.”
- To help users evaluate the stability risk of a dependency update, Dependabot can fetch release notes, changelogs, and commit history in pull requests that update Docker dependencies. For more information, see “Configuration options for the dependabot.yml file.”
- To assist with software security and supply chain risk management, people with read access to a repository can export a software bill of materials (SBOM) for a repository’s dependency graph using the web interface or REST API. The SBOM adheres to the SPDX 2.3 specification. For more information, see “Using the Dependency submission API,” “Exporting a software bill of materials for your repository,” and The Software Package Data Exchange® (SPDX®) Specification Version 2.3 on the SPDX website.

  - New organizations that users create inherit permissions from the instance’s enterprise-level configuration. For more information, see “Disabling or limiting GitHub Actions for your organization.”
  - New repositories that users create within an organization inherit permissions from the organization. For more information, see “Managing GitHub Actions settings for a repository.”
  - New user-owned repositories have a read-only GITHUB_TOKEN. For more information, see “Managing GitHub Actions settings for a repository.”
- To allow workflow authors to pin a required workflow file to a fully validated version, required workflows can be referenced using any branch, tag, or commit SHA from the repository containing the workflow file. For more information, see “Disabling or limiting GitHub Actions for your organization.”
- To enforce required workflows throughout an organization, GitHub Enterprise Server blocks direct pushes to branches where required workflows are enforced. To allow direct pushes for a particular repository, remove the repository as a target for the required workflow. For more information, see “Disabling or limiting GitHub Actions for your organization.”
- To improve performance for workflows that build Go, caching is enabled by default when using the setup-go action. For more information, see “Building and testing Go.”
Organizations
- Organization owners can improve security posture and protect data from threats by enabling the display of organization members’ IP addresses in audit log events. This feature is in beta and is subject to change. For more information, see “Displaying IP addresses in the audit log for your organization.”
- To allow the management of branch protection rules without granting admin access, organization owners can create a custom role with the “Edit repository rules” permission. For more information, see “Managing custom repository roles for an organization.”
- Users of the REST API can programmatically create and update least-privilege roles for repositories using the Custom Repository Roles REST API. The API is generally available, with a breaking change to the API’s endpoint paths. Previously, the API was accessible at /orgs/{org}/custom_roles, and is now accessible at /orgs/{org}/custom-repository-roles. The List custom repository roles in an organization will no longer be available in the next version of the REST API. For more information, see “About custom repository roles” and “Custom Repository Roles” in the REST API documentation.
- Enterprise and organization owners can delete an organization and all of the organization’s repositories using the REST API. After deletion, organization names are locked for 90 days. For more information, see “Organizations” in the REST API documentation.

3.9.0: Changes

Field names and destinations for some service logs on GitHub Enterprise Server have changed. If any tooling or processes in your environment rely on specific field names within logs, or log entries in specific files, the following changes may affect you.
- level is now SeverityText.
- log_message, msg, or message is now Body.
- now is now Timestamp.
- Custom field names such as gh.repo.id or graphql.operation.name use semantic names.
- Log statements that the instance would previously write to auth.log, ldap.log, or ldap-sync.log now appear in containerized logs for github-unicorn if the statement originated from a web request, or in logs for github-resqued if the statement originated from a background job. For more information about containerized logs, see “About system logs.”
For a full list of field mappings, download the OpenTelemetry attribute mapping CSV. This change is part of GitHub’s gradual migration to internal semantic conventions for OpenTelemetry, and additional field names will change in upcoming releases.
On a configured instance, the name for the HAProxy service is now haproxy-frontend. Previously, the name was haproxy. Additionally, on an unconfigured instance, there is a new service named haproxy-pre-config. If your instance forwards logs to an external system, update your rules to reflect these changes. For more information, see “Log forwarding” article
For an instance or organization with 2FA enabled, when a user sets up 2FA, GitHub Enterprise Server suggests an authenticator app (TOTP) by default.
When a person with administrative SSH access to an instance submits a support bundle using either the ghe-support-bundle or ghe-cluster-support-bundle utility, a period for log collection specified with the -p or --period no longer requires quotes to enclose the date value. For more information, see “Command-line utilities.”
To provide additional context within the web interface on an instance where Dependabot alerts are enabled, links to Dependabot alerts in an issue or pull request comment display an improved label and hovercard with alert details.
On an instance with Dependabot alerts enabled, people with write or maintain access to a repository can view or act on Dependabot alerts by default. Custom roles, the security manager role, organization permissions, and notification settings are not affected.
On an instance with a GitHub Advanced Security license and GitHub Connect enabled for the synchronization of actions from GitHub.com, CodeQL code scanning is up to 16% faster. For more information, see “Configuring code scanning for your appliance.”
On an instance with a GitHub Advanced Security license and email configured for notifications, users can receive notifications for secret scanning alerts by watching a repository and choosing “All activity” or "Security alerts". To continue receiving notifications for secret scanning alerts in GitHub Enterprise Server 3.9 and later, users must enable email notifications in the web interface at http(s)://HOSTNAME/settings/notifications under “Watching” by choosing "Email".
On an instance with a GitHub Advanced Security license, secret scanning alerts display whether detected tokens from GitHub are valid.
On an instance with a GitHub Advanced Security license, the enterprise and organization audit logs now display an event when an owner enables or disables a push protection for a custom pattern for a repository, organization, or the enterprise. For more information, see “Reviewing the audit log for your organization” and “Audit log events for your enterprise.”
Users can filter the lists of alerts for Dependabot, code scanning, and secret scanning by repository topic or team in the security overview for an organization. For more information, see “Filtering alerts in security overview.”
In the security overview for an organization, the following improvements apply to the “Security coverage” view during feature enablement.
- To provide insight into the number of GitHub Advanced Security licenses used, active committers for the repository are visible. For repositories where GitHub Advanced Security is not enabled, the number indicates the number of licenses required to enable the feature.
- Unsaved changes are now labeled with a “Modified” tag, and the “Save security settings” button now displays the total number of changes to save.
- While a security feature is being enabled, the “Security coverage” view shows a status of “Updating…” to inform you of the ongoing process.
For more information, see “About security overview.”
In the security overview’s “Security risk” and “Security coverage” views, when a user selects a team from the “Team” drop-down or filters by team, results appear for repositories where the team has write or administrative access or has been granted access to security alerts. Previously, users could only view results for repositories where the team had administrative access or had been granted access to security alerts.
To provide more context within a project, users can share a deep link to a specific issue in a project to have the issue open in the project’s side panel.
Organization owners can create up to five custom repository roles. Previously, the limit was three. For more information, see “About custom repository roles.”
When transferring a repository, users can also rename the repository. For more information, see “Transferring a repository.”
If a user archives a repository, responses from the GraphQL API that include information about the repository now include an archivedAt value with a timestamp representing the archival date.

3.9.0: Backups

Before beginning a backup with GitHub Enterprise Server Backup Utilities 3.9.0 and later, the ghe-host-check utility will now perform a preflight check on the backup host to confirm the software version and disk space requirements. For more information, see the 3.9.0 release in the github/backup-utils repository on GitHub.com.
GitHub Enterprise Server Backup Utilities 3.9.0 allows administrators to view the progress of backup and restoration operations on the backup host using the ghe-backup-progress utility. For more information, see “Configuring backups on your instance.”

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]
On an instance with GitHub Actions enabled, if shared runner groups are configured for the enterprise, the enterprise security overview page may return a 500 error. You can avoid the issue by trying one of the following workarounds.
- Add a runner scale set to the enterprise runner group shared with the repositories.
- Remove access to the enterprise runner group from the affected repositories or organizations.

On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes. [Updated: 2023-09-21]
On an instance with GitHub Actions enabled, ephemeral self-hosted runners do not automatically update to the latest version. Users will need to manually update the runners to the latest version. [Updated: 2023-09-29]
Jobs in a deprecated queue are not processed and may accumulate over time. These jobs are reflected in the monitor dashboard’s “Aqueduct queue depth” graph as an increase in resource_activity. In some cases, a buildup of unprocessed jobs can result in memory exhaustion. If you observe memory exhaustion on your instance and see a high metric for resource_activity, contact GitHub Support. [Updated: 2023-10-10]
When an administrator uses the -p flag with the ghe-support-bundle utility to collect data for a specific number of hours, the utility erroneously collects more logs than necessary. [Updated: 2023-10-13]
The settings for enabling scheduled reminders were added unintentionally to this release. Scheduled reminders are not officially supported. [Updated: 2023-10-17]

3.9.0: Deprecations

Change to command-line utility for management of replication
- On an instance with multiple nodes, people with administrative SSH access to the instance should use ghe-spokesctl for management of Git replication instead of ghe-spokes. For more information, see “Command-line utilities.”
Dependency graph no longer ingests go.sum files
- Because go.sum files are not lock files and may result in false positive Dependabot alerts, on an instance with the dependency graph enabled, the go.sum files are no longer ingested for users’ Go repositories. If Dependabot alerts are enabled, Dependabot will no longer alert users for vulnerabilities in a go.sum file’s dependencies. The dependency graph continues to support go.mod files, the recommended format for Go projects. Use Go 1.17 or higher to ensure your go.mod file contains a comprehensive view of all direct and transitive dependencies. For more information, see “About the dependency graph.”
Only GitHub Actions can publish a GitHub Pages site if source includes symbolic links
- To improve the security of an instance where users deploy sites using GitHub Pages, sites that contain symbolic links will no longer build outside of GitHub Actions. If a user’s site is affected and a site administrator has configured email for the instance, the user will receive an email with instructions about how to fix the error. To continue using symbolic links in the site’s source, the instance must be configured for GitHub Actions, and the user must write a GitHub Actions workflow to use as a publishing source. For more information, see “About GitHub Pages.”

An incorrect comparison vulnerability was identified in GitHub Enterprise Server that allowed commit smuggling by displaying an incorrect diff in a re-opened Pull Request. To do so, an attacker would need write access to the repository. This vulnerability affected all versions of GitHub Enterprise Server and was fixed in versions 3.6.17, 3.7.15, 3.8.8, 3.9.3, and 3.10.1. This vulnerability was reported via the GitHub Bug Bounty program.
