Which packages are affected by GHSA-7j3x-xm4j-jfj7?

GHSA-7j3x-xm4j-jfj7 affects the following packages: io.jenkins.plugins:warnings-ng (Maven). Ecosystems affected: Maven.

How do I fix GHSA-7j3x-xm4j-jfj7?

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.

How do I detect GHSA-7j3x-xm4j-jfj7 in my Maven dependencies?

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.

How do I mitigate GHSA-7j3x-xm4j-jfj7 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-7j3x-xm4j-jfj7?

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.

Is GHSA-7j3x-xm4j-jfj7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-7j3x-xm4j-jfj7 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-7j3x-xm4j-jfj7?

GHSA-7j3x-xm4j-jfj7 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 54th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-7j3x-xm4j-jfj7?

GHSA-7j3x-xm4j-jfj7 is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

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 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.
