Subscriber-to-Administrator escalation via unchecked role update
Published Mar 6, 2020 · Updated Aug 4, 2024
Missing authorization in RegistrationMagic 4.6.0.3 and earlier allows remote authenticated users to promote their accounts to administrator. The edit method in class_rm_user_controller.php accepts rm_user_edit submissions and calls set_user_role without a capability check or nonce. Subscriber-level access to the published /rm_submissions page is sufficient to rewrite the account role, granting full WordPress administrator privileges.
