Description
Ech0 before 4.4.3 protects the PUT /user endpoint with the profile:read scope, a read-only scope, but allows write operations including password changes. An attacker with an admin's profile:read access token can change the admin's password and login to obtain an unrestricted session token that bypasses all scope enforcement.
