GHSA-qcj2-99cg-mppf
MEDIUMGHSA-qcj2-99cg-mppf is a medium-severity (CVSS 5.4) Improper Input Validation vulnerability in org.jenkins-ci.tools:git-parameter. O3 Security confirms whether GHSA-qcj2-99cg-mppf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jenkins Git Parameter Plugin vulnerable to code injection due to inexhaustive parameter check
Real-World Exposure
org.jenkins-ci.tools:git-parameterReal-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 dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.tools:git-parameter. 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.
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.
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.
How O3 protects you
O3 pinpoints whether GHSA-qcj2-99cg-mppf 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-qcj2-99cg-mppf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qcj2-99cg-mppf in your dependencies?
O3 detects GHSA-qcj2-99cg-mppf across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
