CRITICALXWiki Platform vulnerable to remote code execution through the section parameter in Administration as guest
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
XWiki doesn't properly escape the section URL parameter that is used in the code for displaying administration sections. This allows any user with read access to the document XWiki.AdminSheet (by default, everyone including unauthenticated users) to execute code including Groovy code. This impacts the confidentiality, integrity and availability of the whole XWiki instance.
By opening the URL <server>/xwiki/bin/get/Main/WebHome?sheet=XWiki.AdminSheet&viewer=content§ion=%5D%5D%7B%7B%2Fhtml%7D%7D%7B%7Basync%7D%7D%7B%7Bgroovy%7D%7Dservices.logging.getLogger(%22attacker%22).error(%22Attack%20succeeded!%22)%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D&xpage=view where <server> is the URL of the XWiki installation, it can be tested if an XWiki installation is vulnerable. If this causes a log message ERROR attacker - Attack succeeded! to appear in XWiki's log, the installation is vulnerable. In very old versions of XWiki, the attack can be demonstrated with <server>/xwiki/bin/get/XWiki/XWikiPreferences?section=%3C%25println(%22Hello%20from%20Groovy%22)%25%3E&xpage=view which displays admin.hello from groovy as title when the attack succeeds (tested on XWiki 1.7).
Patches
This vulnerability has been patched in XWiki 14.10.14, 15.6 RC1 and 15.5.1.
Workarounds
The fix, which consists of replacing = $services.localization.render("administration.sectionTitle$level", [$sectionName]) = by = $services.localization.render("administration.sectionTitle$level", 'xwiki/2.1', [$sectionName]) =, can be applied manually to the document XWiki.AdminSheet.

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-administration-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-administration-ui to 14.10.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-62pr-qqf7-hh89 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-62pr-qqf7-hh89 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-62pr-qqf7-hh89. 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-62pr-qqf7-hh89 in your dependencies?
O3 detects GHSA-62pr-qqf7-hh89 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
