This vulnerability allows attackers to copy a view inside a folder.

Folders Plugin 6.848.ve3b\_fd7839a\_81 requires POST requests for the affected HTTP endpoint.

**Information disclosure in Folders Plugin**

**SECURITY-3109 / CVE-2023-40338**  
**Severity (CVSS):** Medium  
**Affected plugin: cloudbees-folder**  
**Description:**

Folders Plugin displays an error message when attempting to access the Scan Organization Folder Log if no logs are available.

In Folders Plugin 6.846.v23698686f0f6 and earlier, this error message includes the absolute path of a log file, exposing information about the Jenkins controller file system.

Folders Plugin 6.848.ve3b\_fd7839a\_81 does not display the absolute path of a log file in the error message.

**Improper masking of credentials in Config File Provider Plugin**

**SECURITY-3090 / CVE-2023-40339**  
**Severity (CVSS):** Medium  
**Affected plugin: config-file-provider**  
**Description:**

Config File Provider Plugin 952.va\_544a\_6234b\_46 and earlier does not mask (i.e., replace with asterisks) credentials specified in configuration files when they’re written to the build log.

Config File Provider Plugin 953.v0432a\_802e4d2 masks credentials configured in configuration files if they appear in the build log.

**Improper masking of credentials in NodeJS Plugin**

**SECURITY-3196 / CVE-2023-40340**  
**Severity (CVSS):** Medium  
**Affected plugin: nodejs**  
**Description:**

NodeJS Plugin integrates with Config File Provider Plugin to specify custom NPM settings, including credentials for authentication, in a Npm config file.

NodeJS Plugin 1.6.0 and earlier does not properly mask (i.e., replace with asterisks) credentials specified in the Npm config file in Pipeline build logs.

NodeJS Plugin 1.6.0.1 masks credentials specified in the Npm config file in Pipeline build logs.

**CSRF vulnerability in Blue Ocean Plugin allows capturing credentials**

**SECURITY-3116 / CVE-2023-40341**  
**Severity (CVSS):** Medium  
**Affected plugin: blueocean**  
**Description:**

Blue Ocean Plugin 1.27.5 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to connect to an attacker-specified URL, capturing GitHub credentials associated with an attacker-specified job.

This issue is due to an incomplete fix of SECURITY-2502.

Blue Ocean Plugin 1.27.5.1 uses the configured SCM URL, instead of a user-specified URL provided as a parameter to the HTTP endpoint.

**CSRF vulnerability and missing permission checks in Fortify Plugin allow capturing credentials**

**SECURITY-3115 / CVE-2023-4301 (CSRF), CVE-2023-4302 (missing permission check)**  
**Severity (CVSS):** Medium  
**Affected plugin: fortify**  
**Description:**

Fortify Plugin 22.1.38 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

Fortify Plugin 22.2.39 requires POST requests and the appropriate permissions for the affected HTTP endpoints.

**HTML injection vulnerability in Fortify Plugin**

**SECURITY-3140 / CVE-2023-4303**  
**Severity (CVSS):** Medium  
**Affected plugin: fortify**  
**Description:**

Fortify Plugin 22.1.38 and earlier does not escape the error message for a form validation method. This results in an HTML injection vulnerability.

Since Jenkins 2.275 and LTS 2.263.2, a security hardening for form validation responses prevents JavaScript execution, so no scripts can be injected.

Fortify Plugin 22.2.39 removes HTML tags from the error message.

**Stored XSS vulnerability in Flaky Test Handler Plugin**

**SECURITY-3223 / CVE-2023-40342**  
**Severity (CVSS):** High  
**Affected plugin: flaky-test-handler**  
**Description:**

Flaky Test Handler Plugin 1.2.2 and earlier does not escape JUnit test contents when showing them on the Jenkins UI.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control JUnit report file contents.

Flaky Test Handler Plugin 1.2.3 escapes JUnit test contents when showing them on the Jenkins UI.

**Non-constant time token comparison in Tuleap Authentication Plugin**

**SECURITY-3229 / CVE-2023-40343**  
**Severity (CVSS):** Low  
**Affected plugin: tuleap-oauth**  
**Description:**

Tuleap Authentication Plugin 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal.

This could potentially allow attackers to use statistical methods to obtain a valid authentication token.

Tuleap Authentication Plugin 1.1.21 uses a constant-time comparison when validating authentication tokens.

**Missing permission check in Delphix Plugin allows enumerating credentials IDs**

**SECURITY-3214 (1) / CVE-2023-40344**  
**Severity (CVSS):** Medium  
**Affected plugin: delphix**  
**Description:**

Delphix Plugin 3.0.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.

An enumeration of credentials IDs in Delphix Plugin 3.0.3 requires the appropriate permissions.

**Exposure of system-scoped credentials in Delphix Plugin**

**SECURITY-3214 (2) / CVE-2023-40345**  
**Severity (CVSS):** Medium  
**Affected plugin: delphix**  
**Description:**

Delphix Plugin 3.0.2 and earlier does not set the appropriate context for credentials lookup, allowing the use of System-scoped credentials otherwise reserved for the global configuration.

This allows attackers with Overall/Read permission to access and capture credentials they are not entitled to.

Delphix Plugin 3.0.3 defines the appropriate context for credentials lookup.

**Stored XSS vulnerability in Shortcut Job Plugin**

**SECURITY-3071 / CVE-2023-40346**  
**Severity (CVSS):** High  
**Affected plugin: shortcut-job**  
**Description:**

Shortcut Job Plugin 0.4 and earlier does not escape the shortcut redirection URL.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure shortcut jobs.

Shortcut Job Plugin 0.5 escapes the shortcut redirection URL.

**Exposure of system-scoped credentials in Maven Artifact ChoiceListProvider (Nexus) Plugin**

**SECURITY-3153 / CVE-2023-40347**  
**Severity (CVSS):** Medium  
**Affected plugin: maven-artifact-choicelistprovider**  
**Description:**

Maven Artifact ChoiceListProvider (Nexus) Plugin 1.14 and earlier does not set the appropriate context for credentials lookup, allowing the use of System-scoped credentials otherwise reserved for the global configuration.

This allows attackers with Item/Configure permission to access and capture credentials they are not entitled to.

**Unsafe default behavior and information disclosure in Gogs Plugin webhook**

**SECURITY-2894 / CVE-2023-40348 (information disclosure), CVE-2023-40349 (insecure default)**  
**Severity (CVSS):** Medium  
**Affected plugin: gogs-webhook**  
**Description:**

Gogs Plugin provides a webhook endpoint at /gogs-webhook that can be used to trigger builds of jobs. In Gogs Plugin 1.0.15 and earlier, an option to specify a Gogs secret for this webhook is provided, but not enabled by default.

This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified job name.

Additionally, the output of the webhook endpoint includes whether a job corresponding to the attacker-specified job name exists, even if the attacker has no permission to access it.

**Stored XSS vulnerability in Docker Swarm Plugin**

**SECURITY-2811 / CVE-2023-40350**  
**Severity (CVSS):** High  
**Affected plugin: docker-swarm**  
**Description:**

Docker Swarm Plugin processes Docker responses to generate the Docker Swarm Dashboard view.

Docker Swarm Plugin 1.11 and earlier does not escape values returned from Docker before inserting them into the Docker Swarm Dashboard view. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control responses from Docker.

**CSRF vulnerability in Favorite View Plugin**

**SECURITY-3201 / CVE-2023-40351**  
**Severity (CVSS):** Medium  
**Affected plugin: favorite-view**  
**Description:**

Favorite View Plugin 5.v77a\_37f62782d and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.
