CRITICALMissing Authorization to enable or disable users in org.xwiki.platform:xwiki-platform-user-profile-ui
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.

org.xwiki.platform:xwiki-platform-user-profile-ui☕org.xwiki.platform:xwiki-platform-user-profile-uiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Any user (logged in or not) with access to the page XWiki.XWikiUserProfileSheet can enable or disable any user profile. This might allow to a disabled user to re-enable themselves, or to an attacker to disable any user of the wiki.
Patches
The problem has been patched in XWiki 13.10.7, 14.5RC1 and 14.4.2.
Workarounds
The problem can be patched immediately by editing the page XWiki.XWikiUserProfileSheet in the wiki and by performing the changes contained in https://github.com/xwiki/xwiki-platform/commit/5be1cc0adf917bf10899c47723fa451e950271fa.

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-user-profile-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-user-profile-ui to 13.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p5v9-g8w8-5q4v 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-p5v9-g8w8-5q4v 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-p5v9-g8w8-5q4v. 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-p5v9-g8w8-5q4v in your dependencies?
O3 detects GHSA-p5v9-g8w8-5q4v across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
