Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission plugin for WordPress is vulnerable to Authorization Bypass in all versions up to, and including, 4.3.11. This is due to a missing check for the `users_can_register` site option in the frontend registration handler, allowing unauthenticated POST requests to the init-hooked handler to create accounts regardless of the site's registration setting. This makes it possible for unauthenticated attackers to register new user accounts on sites where user registration has been disabled by the administrator.
