Description
Impact
It's possible for any user knowing the ID of a notification filter preference of another user, to enable/disable it or even delete it. The impact is that the target user might start loosing notifications on some pages because of this. This vulnerability is present in XWiki since 13.2-rc-1.
Patches
The vulnerability has been patched in XWiki 14.10.21, 15.5.5, 15.10.1, 16.0-rc-1. The patch consists in checking properly the rights of the user before performing any action on the filters.
Workarounds
It's possible to fix manually the vulnerability by editing the document XWiki.Notifications.Code.NotificationPreferenceService to apply the changes performed in this commit e8acc9d8e6af7dfbfe70716ded431642ae4a6dd4.

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-notifications-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-notifications-ui to 14.10.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r95w-889q-x2gx 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-r95w-889q-x2gx 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-r95w-889q-x2gx. 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-r95w-889q-x2gx in your dependencies?
O3 detects GHSA-r95w-889q-x2gx across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
