Technical details

The vulnerability is a missing authorization check (CWE-862) in the POST /userBusiness/updateOneValueByKeyIdAndType endpoint that allows an authenticated user to modify their own UserRole record. An attacker with any valid tenant user credential can send a request with type=UserRole, their own user ID, and a target role ID list to self-escalate privileges. The endpoint fails to validate that the requester should not be able to modify their own role assignments, allowing direct privilege elevation from low-privilege to administrator.
