Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

brakeman Plugin 0.12 and earlier did not escape values received from parsed JSON files when rendering them, resulting in a stored cross-site scripting vulnerability.

This vulnerability can be exploited by users able to control the Brakeman post-build step input data.\n\nbrakeman Plugin 0.13 escape affected values from the parsed file as they are recorded.

This fix is only applied to newly recorded data after a fixed version of the plugin is installed; historical data may still contain unsafe values.

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:brakeman. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update org.jenkins-ci.plugins:brakeman to 0.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7q9r-vhg2-789w is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-7q9r-vhg2-789w is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-7q9r-vhg2-789w. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
