Official description

X-SpringBoot through 6.0 lacks object-level authorization in user management endpoints, allowing sub-administrators to modify or delete users without ownership verification. Attackers with user-management permissions can reset passwords for any account including the super administrator, rebind roles, or delete users via POST /sys/user/update and POST /sys/user/delete endpoints.
