Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update jenkins.ci.plugins.computerqueue:computer-queue-plugin to 1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qg66-xv7v-m834 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.
