EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-rvh4-g2rj-hr9c plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Jenkins Warnings Next Generation Plugin prior to 9.10.3, 9.7.1, 9.5.2, and 9.0.2 does not restrict the name of a file when configuring a custom ID.
This allows attackers with Item/Configure permission to write and read specific files with a hard-coded suffix on the Jenkins controller file system.
Jenkins Warnings Next Generation Plugin 9.10.3, 9.7.1, 9.5.2, and 9.0.2 checks for the presence of prohibited directory separator characters in the custom ID.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.jenkins.plugins:warnings-ng to 9.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rvh4-g2rj-hr9c 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-rvh4-g2rj-hr9c can be triaged on real exposure rather than presence alone.
Tailored to GHSA-rvh4-g2rj-hr9c. 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-rvh4-g2rj-hr9c in your dependencies?
O3 Security finds GHSA-rvh4-g2rj-hr9c across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
