Description
Craft CMS from 5.0.0 before 5.11.2 contains a privilege escalation vulnerability that allows unauthenticated public registrants to reclaim deactivated non-admin accounts while retaining their direct permissions. Attackers can register using a deactivated account, set a new password, and inherit permissions stored in userpermissions_users, enabling privileged account takeover when email verification is disabled.
