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 list some users who are normally not viewable from subwiki by requesting users on a subwiki which allows only global users with uorgsuggest.vm. This issue only concerns hidden users from main wiki.
Note that the disclosed information are the username and the first and last name of users, no other information is leaked.
Patches
The problem has been patched on XWiki 13.10.8, 14.4.3 and 14.7RC1.
Workarounds
It's possible to workaround this vulnerability by patching directly uorgsuggest.vm to apply the same changes as in https://github.com/xwiki/xwiki-platform/pull/1883.

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 13.10.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vvp7-r422-rx83 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-vvp7-r422-rx83 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-vvp7-r422-rx83. 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-vvp7-r422-rx83 in your dependencies?
O3 detects GHSA-vvp7-r422-rx83 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
