How do I detect CVE-2015-0265 in my Maven dependencies?

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

How do I mitigate CVE-2015-0265 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-2015-0265 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2015-0265, including 1 in-the-wild exploitation observed on GitHub and other sources.
