Technical details
The vulnerability is a broken object-level authorization (CWE-639) in the Users::form() method. A secondary administrator (user_type=1, user_id != 1) can modify the primary administrator's (user_id=1) email address because user_email is not in PROTECTED_FIELDS and form() lacks authorization checks equivalent to those added to change_password(). An attacker can then initiate the public password-recovery flow, which resolves accounts by email, receive the reset token, and assume control of the primary administrator account. The vulnerability requires authenticated access as a secondary administrator.
