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

Jenkins Configuration as Code Plugin prior to 1.55.1, 1.54.1, 1.53.1, and 1.47.1 does not use a constant-time comparison when checking whether two authentication tokens are equal.

This could potentially allow attackers to use statistical methods to obtain a valid authentication token.

Configuration as Code Plugin 1.55.1, 1.54.1, 1.53.1, and 1.47.1 now uses a constant-time comparison when validating authentication tokens.

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:configuration-as-code. 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 io.jenkins:configuration-as-code to 1.55.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fpj7-9xm6-8hgr 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-fpj7-9xm6-8hgr 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-fpj7-9xm6-8hgr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
