Cross-site Scripting in Jenkins JUnit Plugin

CVE-2023-25761GHSA-ph74-8rgx-64c5

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.jenkins-ci.plugins:junit 1166.1168.vd6b_8042a_06de), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Jenkins JUnit Plugin 1166.va436e268e972 and earlier does not escape test case class names in JavaScript expressions, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control test case class names in the JUnit resources processed by the plugin.

# Patch Next advisory brief: CVE-2023-25761

Advisory: Cross-site Scripting in Jenkins JUnit Plugin
IDs: CVE-2023-25761, GHSA-ph74-8rgx-64c5
Record: https://patchnext.com/advisories/cve-2023-25761 (revision 1, source checked 26 Oct 2026, 16:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.jenkins-ci.plugins:junit 1166.1168.vd6b_8042a_06de. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:junit: affected <= 1166.va; fixed in 1166.1168.vd6b_8042a_06de

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:junit: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:junit.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-ph74-8rgx-64c5 (GitHub-reviewed advisory GHSA-ph74-8rgx-64c5 lists affected ranges: Maven org.jenkins-ci.plugins:junit >=0 <=1166.va)
