How do I fix CVE-2022-31777?

A fix is available for CVE-2022-31777; check the affected-versions list above or the advisory for the patched release of org.apache.spark:spark-core_2.9.3, then make sure no transitive dependency still pins the vulnerable range.

How do I detect CVE-2022-31777 in my Maven, PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.spark:spark-core_2.9.3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2022-31777 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-2022-31777 actively exploited in the wild?
