What is CVE-2021-4368?

The Frontend File Manager plugin for WordPress, prior to version 18.2, contains a vulnerability that permits authenticated users with subscriber-level access to modify critical plugin settings. This flaw arises from insufficient capability checks and the absence of a security nonce within the wpfm_save_settings AJAX action. Attackers can exploit this vulnerability to alter settings, such as permitted file types for uploads, potentially leading to remote code execution through related security gaps.
