Description

The UserPro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.1. This is due to missing nonce validation in the &#39;admin_page&#39;, &#39;userpro_verify_user&#39; and &#39;verifyUnverifyAllUsers&#39; functions. This makes it possible for unauthenticated attackers to modify the role of verified users to elevate verified user privileges to that of any user such as &#39;administrator&#39; via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
