Description
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. A vulnerability exists in versions prior to 12.6.88, 12.10.4, and 13.0. The script service method used to reset the authentication failures record can be executed by any user with Script rights and does not require Programming rights. An attacher with script rights who is able to reset the authentication failure record might perform a brute force attack, since they would be able to virtually deactivate the mechanism introduced to mitigate those attacks. The problem has been patched in version 12.6.8, 12.10.4 and 13.0. There are no workarounds aside from upgrading.

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-security-authentication-script. 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-security-authentication-script to 12.6.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-32729 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 CVE-2021-32729 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 CVE-2021-32729. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
