Frontend File Manager <= 18.2 - Authenticated Settings Change leading to Arbitrary File Upload

Missing Authorization
CVE CVE-2021-4368
CVSS Critical (9.9)
Publicly Published July 12, 2021

Researcher Jerome Bruandet
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.
