GHSA-7j3x-xm4j-jfj7
MEDIUMGHSA-7j3x-xm4j-jfj7 is a medium-severity (CVSS 4.3) CWE-862 vulnerability in io.jenkins.plugins:warnings-ng. O3 Security confirms whether GHSA-7j3x-xm4j-jfj7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Missing permission checks in Jenkins Warnings Next Generation Plugin allow listing workspace contents
Real-World Exposure
io.jenkins.plugins:warnings-ngReal-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 Warnings Next Generation Plugin 8.4.4 and earlier does not perform permission checks in methods implementing form validation.
This allows attackers with Item/Read permission but without Item/Workspace or Item/Configure permission to check whether attacker-specified file patterns match workspace contents. A sequence of requests can be used to effectively list workspace contents.
Jenkins Warnings Next Generation Plugin 8.5.0 requires Item/Configure permission to validate patterns with workspace contents.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:warnings-ng. 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 io.jenkins.plugins:warnings-ng to 8.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7j3x-xm4j-jfj7 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-7j3x-xm4j-jfj7 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-7j3x-xm4j-jfj7. 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-7j3x-xm4j-jfj7 in your dependencies?
O3 detects GHSA-7j3x-xm4j-jfj7 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
