GHSA-x234-mg7q-m8g8
CRITICALXWiki Platform vulnerable to reflected cross-site scripting via xredirect parameter in deletespace template
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
Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the deletespace template to perform a XSS, e.g. by using URL such as:
xwiki/bin/deletespace/Sandbox/?xredirect=javascript:alert(document.domain)
This vulnerability exists since XWiki 3.4-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 template deletespace.vm 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-web-templates. 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-web-templates to 14.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x234-mg7q-m8g8 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-x234-mg7q-m8g8 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-x234-mg7q-m8g8. 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-x234-mg7q-m8g8 in your dependencies?
O3 detects GHSA-x234-mg7q-m8g8 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
