The File Manager Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 8.3.9.

This makes it possible for unauthenticated attackers to upload arbitrary files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
