GHSA-g9fx-6j5c-grmw is a high-severity (CVSS 8.8) OS Command Injection vulnerability in org.jenkins-ci.plugins.workflow:workflow-cps-global-lib. O3 Security confirms whether GHSA-g9fx-6j5c-grmw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Jenkins Pipeline: Shared Groovy Libraries Plugin prior to 561.va_ce0de3c2d69, 2.21.1, and 2.18.1 uses the same checkout directories for distinct SCMs for Pipeline libraries, allowing attackers with Item/Configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

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.plugins.workflow:workflow-cps-global-lib. 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.plugins.workflow:workflow-cps-global-lib to 561.va or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g9fx-6j5c-grmw 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-g9fx-6j5c-grmw 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-g9fx-6j5c-grmw. 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-g9fx-6j5c-grmw in your dependencies?
O3 detects GHSA-g9fx-6j5c-grmw across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
