Front End Users <= 3.2.24 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Front End Users plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.2.24. This is due to missing or incorrect nonce validation on several functions such as Mass_Delete_EWD_FEUP_Users, Delete_All_EWD_FEUP_Users, and Mass_Delete_EWD_FEUP_Fields. This makes it possible for unauthenticated attackers to potentially delete users, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
