Official description

The Melapress Login Security plugin for WordPress is vulnerable to Authentication Bypass due to missing authorization within the get_valid_user_based_on_token() function in versions 2.1.0 to 2.1.1. This makes it possible for unauthenticated attackers who know an arbitrary user meta value to bypass authentication checks and log in as that user.
