LearnPress – WordPress LMS Plugin <= 4.0.0 - Cross-Site Request Forgery to Privilege Escalation

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.0.0. This is due to missing or incorrect nonce validation on the filter_users functions. This makes it possible for unauthenticated attackers to elevate their privileges to that of a teacher via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
