CVE-2021-32729
A user without PR can reset user authentication failures information
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.

GitHub AdvisoriesGHSA-m738-3rc4-5xv3
A user without PR can reset user authentication failures information
Impact
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 as it should have. Note that being able to reset the authentication failure record mean that an attacker with script right might use it to try performing a bruteforce attack since she'd been able to virtually deactivate the mechanism introduced to mitigate those attacks.
Patches
The problem has been patched in version 12.6.8, 12.10.4 and 13.0.
Workarounds
There's no workaround besides upgrading and being careful on which user should have Script right access. Note that any bruteforce attack on the authentication should be visible in the logs since the authentication failures are logged.
