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

How do I mitigate CVE-2025-49586 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2025-49586 actively exploited in the wild?

Description

Impact

Any XWiki user with edit right on at least one App Within Minutes application (the default for all users XWiki) can obtain programming right/perform remote code execution by editing the application. The detailed reproduction steps can be found in the original bug report.

Patches

This vulnerability has been fixed in XWiki 17.0.0, 16.4.7, and 16.10.3.

Workarounds

Restricting edit rights on all existing App Within Minutes applications to trusted users mitigates at least the PoC exploit, but we can't exclude that there are other ways to exploit this vulnerability.
