ACPT (Premium) <= 2.0.66 - Unauthenticated Privilege Escalation via 'acpt_form_post_id' Parameter
The ACPT (Premium) plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.66. This is due to missing authorization in the submit() function, which allows unauthenticated form submissions to control the target user ID before calling wp_update_user(). This makes it possible for unauthenticated attackers to overwrite any WordPress user's email address and password, including an administrator's, and take over the account. Successful exploitation requires a public ACPT user form that permits anonymous submissions.
