GHSA-4xm7-5q79-3fch
CRITICALGHSA-4xm7-5q79-3fch is a critical-severity (CVSS 9.6) CWE-87 vulnerability in org.xwiki.platform:xwiki-platform-appwithinminutes-ui. O3 Security confirms whether GHSA-4xm7-5q79-3fch is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
XWiki Platform vulnerable to reflected cross-site scripting via xredirect parameter in DeleteApplication page
Blast Radius
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
Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the DeleteApplication page to perform a XSS, e.g. by using URL such as:
xwiki/bin/view/AppWithinMinutes/DeleteApplication?appName=Menu&resolve=true&xredirect=javascript:alert(document.domain)
This vulnerability exists since XWiki 6.2-milestone-1.
Patches
The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.
Workarounds
It's possible to workaround the vulnerability by editing the page AppWithinMinutes.DeleteApplication to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets.

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 14.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4xm7-5q79-3fch 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-4xm7-5q79-3fch 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-4xm7-5q79-3fch. 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-4xm7-5q79-3fch in your dependencies?
O3 detects GHSA-4xm7-5q79-3fch across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
