The Awesome Support - WordPress HelpDesk & Support Plugin for WordPress is vulnerable to authorization bypass due to missing capability checks in all versions up to, and including, 6.3.6. This is due to the 'wpas_do_mr_activate_user' function not verifying that a user has permission to modify other users' roles, combined with a nonce reuse vulnerability where public registration nonces are valid for privileged actions because all actions share the same nonce namespace. This makes it possible for unauthenticated attackers to demote administrators to low-privilege roles via the 'wpas-do=mr_activate_user' action with a user-controlled 'user_id' parameter, granted they can access the publicly available registration/submit ticket page to extract a valid nonce.

The advisory is available at wordfence.com. This vulnerability was named CVE-2025-12641. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
