Advisory

Source description from Wordfence Intelligence, credited to James Hooker.

The Registration Forms – User Profile, Custom Registration Form, Login Form, Invitation-Based Registrations plugin for WordPress is vulnerable to authentication bypass in versions 2.0.14 - 2.0.15 . This is due to a lack of validation of user input in a login request to the plugin. This makes it possible for unauthenticated attackers to authenticate as an administrator when supplying a site administrators user id.
