How severe is CVE-2022-20615?

CVE-2022-20615 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-20615?

CVE-2022-20615 affects the following packages: org.jenkins-ci.plugins:matrix-project (Maven), org.jenkins-ci.plugins:matrix-project (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-20615?

Update org.jenkins-ci.plugins:matrix-project to 1.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-20615 is resolved across your whole dependency graph.

How do I detect CVE-2022-20615 in my Maven dependencies?

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

How do I mitigate CVE-2022-20615 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 CVE-2022-20615 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-20615 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 CVE-2022-20615?

CVE-2022-20615 has an EPSS (Exploit Prediction Scoring System) score of 81.8%, placing it in the 100th 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. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.
