## Technical details

The PUT /sys/user/changeDepartChargePerson endpoint lacks authorization checks (missing @RequiresPermissions annotation) and does not validate that the caller has permission to modify the target user or department. An authenticated attacker can supply arbitrary userId, departId, and status values to set user_identity to 2 (department head) and add/remove department IDs from sys_user.depart_ids, bypassing privilege escalation controls that other endpoints in the same controller enforce.
