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.
