GHSA-4wc6-hqv9-qc97
CRITICALXWiki Platform vulnerable to stored cross-site scripting in ClassEditSheet page via name parameters
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

org.xwiki.platform:xwiki-platform-appwithinminutes-ui☕org.xwiki.platform:xwiki-platform-appwithinminutes-ui☕org.xwiki.platform:xwiki-platform-appwithinminutes-uiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
A stored XSS can be exploited by users with edit rights by adding a AppWithinMinutes.FormFieldCategoryClass class on a page and setting the payload on the page title.
Then, any user visiting /xwiki/bin/view/AppWithinMinutes/ClassEditSheet executes the payload.
See https://jira.xwiki.org/browse/XWIKI-20365 for me details.
Patches
The issue has been patched on XWiki 14.4.8, 14.10.4, and 15.0 ?
Workarounds
The issue can be fixed by updating AppWithinMinutes.ClassEditSheet with this patch.

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-appwithinminutes-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-appwithinminutes-ui to 14.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4wc6-hqv9-qc97 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-4wc6-hqv9-qc97 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-4wc6-hqv9-qc97. 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-4wc6-hqv9-qc97 in your dependencies?
O3 detects GHSA-4wc6-hqv9-qc97 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
