Description

Jenkins Custom Build Properties Plugin 2.79.vc095ccc85094 and earlier does not escape property values and build display names on the Custom Build Properties and Build Summary pages, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to set or change these values. Custom Build Properties Plugin 2.82.v16d5b_d3590c7 escapes property values and build display names on the Custom Build Properties and Build Summary pages.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update io.jenkins.plugins:custom-build-properties to 2.82.v16d5b or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-46686 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.
