Vulnerability details
The vulnerability allows a remote privileged user to delete higher-privileged groups, revoke group-based administrative access, and disrupt administration.
The vulnerability exists due to incorrect authorization in phpMyFAQ's group confirmation and deletion endpoints when processing target group identifiers with security.permLevel=medium, without verifying authority over the target group's permissions. A remote privileged user can use delegated delgroup permission to submit a target identifier to /admin/group/confirm, obtain a valid CSRF token, and submit /admin/group/delete to remove the group, its memberships, and its permission mappings.
