How severe is GHSA-39r3-h8q6-2phq?

GHSA-39r3-h8q6-2phq has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-39r3-h8q6-2phq?

GHSA-39r3-h8q6-2phq affects the following packages: org.jenkins-ci.plugins:embeddable-build-status (Maven). Ecosystems affected: Maven.

How do I fix GHSA-39r3-h8q6-2phq?

Update org.jenkins-ci.plugins:embeddable-build-status to 2.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-39r3-h8q6-2phq is resolved across your whole dependency graph.

How do I detect GHSA-39r3-h8q6-2phq in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:embeddable-build-status, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-39r3-h8q6-2phq if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-39r3-h8q6-2phq actively exploited in the wild?

No public exploit code has been indexed for GHSA-39r3-h8q6-2phq 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-39r3-h8q6-2phq?

GHSA-39r3-h8q6-2phq has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 63th 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-39r3-h8q6-2phq?
