GHSA-3738-p9x3-mv9r
CRITICALXWiki Platform vulnerable to privilege escalation via properties with wiki syntax that are executed with wrong author
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
It's possible to use the right of an existing document content author to execute a text area property.
To reproduce:
- As an admin with programming rights, create a new user without script or programming right.
- Login with the freshly created user.
- Insert the following text in source mode in the about section:
{{groovy}}println("hello from groovy!"){{/groovy}}
- Click "Save & View"
Patches
This has been patched in XWiki 14.10, 14.4.7, and 13.10.11.

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-oldcore. 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-oldcore to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3738-p9x3-mv9r 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-3738-p9x3-mv9r 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-3738-p9x3-mv9r. 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-3738-p9x3-mv9r in your dependencies?
O3 detects GHSA-3738-p9x3-mv9r across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
