Description
XWiki Platform Filter UI provides a generic user interface to convert from a XWiki Filter input stream to an output stream with settings for each stream. Starting with versions 6.0-milestone-2 and 5.4.4 and prior to versions 12.10.11, 14.0-rc-1, 13.4.7, and 13.10.3, XWiki Platform Filter UI contains a possible cross-site scripting vector in the Filter.FilterStreamDescriptorForm wiki page related to pretty much all the form fields printed in the home page of the application. The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, and 13.10.3. The easiest workaround is to edit the wiki page Filter.FilterStreamDescriptorForm (with wiki editor) according to the instructions in the GitHub Security Advisory.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-filter-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-filter-ui to 12.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-29258 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2022-29258 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2022-29258. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-29258 in your dependencies?
O3 detects CVE-2022-29258 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
