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

An exposure of sensitive information vulnerability exists in Jenkins GitHub Pull Request Builder Plugin version 1.39.0 and older in GhprbCause.java that allows an attacker with local file system access to obtain GitHub credentials. Since 1.40.0, the plugin no longer stores serialized objects containing the credential on disk. Builds started before the plugin was updated to 1.40.0 will retain the encoded credentials on disk. We strongly recommend revoking old GitHub credentials used in Jenkins. We’re providing a script for use in the Script Console that will attempt to remove old stored credentials from build.xml files.

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:ghprb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:ghprb to 1.40.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hr74-2j5v-ghfv is resolved across your whole dependency graph.

  3. Workarounds

    Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
