Description

Since Jenkins 2.320 and LTS 2.332.1, help icon tooltips no longer escape the feature name, effectively undoing the fix for SECURITY-1955.

This vulnerability is known to be exploitable by attackers with Job/Configure permission.

Jenkins 2.356, LTS 2.332.4 and LTS 2.346.1 addresses this vulnerability, the feature name in help icon tooltips is now escaped.

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.main:jenkins-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.main:jenkins-core to 2.356 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-62wf-24c4-8r76 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.
