XWiki vulnerable to a reflected XSS via xredirect parameter in DeleteApplication
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.

Description
Impact
A reflected XSS vulnerability in XWiki allows an attacker to send a victim to a URL with a deletion confirmation message on which the attacker-supplied script is executed when the victim clicks the "No" button. When the victim has admin or programming right, this allows the attacker to execute basically arbitrary actions on the XWiki installation including remote code execution.
Patches
This vulnerability has been patched in XWiki 16.10.10, 17.4.2 and 17.5.0 by using the affected URL parameter only in the intended context.
Workarounds
The patch can be manually applied to the templates that are present in the WAR. A restart of XWiki is needed for the changes to be applied.

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-flamingo-skin-resources. 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-flamingo-skin-resources to 16.10.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7vpr-jm38-wr7w 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-7vpr-jm38-wr7w 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-7vpr-jm38-wr7w. 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-7vpr-jm38-wr7w in your dependencies?
O3 detects GHSA-7vpr-jm38-wr7w across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
