Description

Jenkins Health Advisor by CloudBees Plugin 374.v194b_d4f0c8c8 and earlier does not escape responses from the Jenkins Health Advisor server, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control Jenkins Health Advisor server responses.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:cloudbees-jenkins-advisor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:cloudbees-jenkins-advisor to 374.376.v3a_41a_a_142efe or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xrpq-4g9w-qrwj is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
