Which packages are affected by CVE-2020-2317?

CVE-2020-2317 affects the following packages: org.jvnet.hudson.plugins:findbugs (Maven). Ecosystems affected: Maven.

How do I fix CVE-2020-2317?

The records we use list no patched version of org.jvnet.hudson.plugins:findbugs for CVE-2020-2317. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

How do I detect CVE-2020-2317 in my Maven dependencies?

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

How do I mitigate CVE-2020-2317 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-2020-2317 actively exploited in the wild?
