How do I fix CVE-2018-12533?

The records we use list no patched version of org.richfaces:richfaces-core for CVE-2018-12533. 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-2018-12533 in my Maven dependencies?

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

How do I mitigate CVE-2018-12533 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2018-12533 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2018-12533, including 2 in-the-wild exploitations observed on GitHub and other sources.
