GHSA-22q5-9phm-744v
XWiki allows unregistered users to access private pages information through REST endpoint
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.

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Protected pages are listed when requesting the REST endpoints /rest/wikis/[wikiName]/pages even if the user doesn't have view rights on them.
It's particularly true if the entire wiki is protected with "Prevent unregistered user to view pages": the endpoint would still list the pages of the wiki (actually it only impacts the main wiki due to XWIKI-22639).
Patches
The problem has been patched in XWiki 15.10.14, 16.4.6, 16.10.0RC1. In those versions the endpoint can still be requested but the result is filtered out based on pages rights.
Workarounds
There's no workaround except upgrading or applying manually the changes of the commits (see references) in xwiki-platform-rest-server and recompiling / rebuilding it.

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-rest-server. 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-rest-server to 15.10.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-22q5-9phm-744v 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-22q5-9phm-744v 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-22q5-9phm-744v. 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-22q5-9phm-744v in your dependencies?
O3 detects GHSA-22q5-9phm-744v across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
