GHSA-xjfw-5vv5-vjq2
HIGHGHSA-xjfw-5vv5-vjq2 is a high-severity (CVSS 7.4) CWE-80 vulnerability in org.xwiki.platform:xwiki-platform-filter-ui. O3 Security confirms whether GHSA-xjfw-5vv5-vjq2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
We found a possible XSS vector in the Filter.FilterStreamDescriptorForm wiki page related to pretty much all the form fields printed in the home page of the application.
Patches
The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3.
Workarounds
The easiest workaround is to edit the wiki page Filter.FilterStreamDescriptorForm (with wiki editor) and change the lines
<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$request.get($descriptorId)#else$descriptor.defaultValue#end"/>
#else
<input type="text" id="$descriptorId" name="$descriptorId"#if($request.get($descriptorId))value="$request.get($descriptorId)"#end/>
into
<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$escapetool.xml($request.get($descriptorId))#else$descriptor.defaultValue#end"/>
#else
<input type="text" id="$descriptorId" name="$descriptorId"#if($request.get($descriptorId))value="$escapetool.xml($request.get($descriptorId))"#end/>

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 GHSA-xjfw-5vv5-vjq2 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 GHSA-xjfw-5vv5-vjq2 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 GHSA-xjfw-5vv5-vjq2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-xjfw-5vv5-vjq2 in your dependencies?
O3 detects GHSA-xjfw-5vv5-vjq2 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
