CVE-2021-4368
The Frontend File Manager plugin for WordPress is vulnerable to Authenticated Settings Change in versions up to, and including, 18.2.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The Frontend File Manager plugin for WordPress is vulnerable to Authenticated Settings Change in versions up to, and including, 18.2. This is due to lacking capability checks and a security nonce, all on the wpfm_save_settings AJAX action. This makes it possible for subscriber-level attackers to edit the plugin settings, such as the allowed upload file types. This can lead to remote code execution through other vulnerabilities.
