MEDIUMXWiki Platform CSRF in the job scheduler
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
It is possible to schedule/trigger/unschedule existing jobs by having an admin visit the Job Scheduler page through a predictable URL, for example by embedding such an URL in any content as an image.
To reproduce in an XWiki installation, open <xwiki-host>:/xwiki/bin/view/Scheduler/?do=trigger&which=Scheduler.NotificationEmailDailySender as a user with admin rights. If there is no error message that indicates the CSRF token is invalid, the installation is vulnerable.
Patches
The vulnerability has been fixed on XWiki 14.10.19, 15.5.5, and 15.9.
Workarounds
Modify the Scheduler.WebHome page following this patch.

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-scheduler-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-scheduler-ui to 14.10.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j2r6-r929-v6gf 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-j2r6-r929-v6gf 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-j2r6-r929-v6gf. 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-j2r6-r929-v6gf in your dependencies?
O3 detects GHSA-j2r6-r929-v6gf across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
