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 Git Parameter Plugin implements a choice build parameter that lists the configured Git SCM’s branches, tags, pull requests, and revisions.

Git Parameter Plugin 439.vb_0e46ca_14534 and earlier does not validate that the Git parameter value submitted to the build matches one of the offered choices.

This allows attackers with Item/Build permission to inject arbitrary values into Git parameters.

Git Parameter Plugin 444.vca_b_84d3703c2 validates that the Git parameter value submitted to the build matches one of the offered choices.

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.tools:git-parameter, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.tools:git-parameter to 444.vca or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qcj2-99cg-mppf 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.
