CVE-2021-4368Frontend File Manager <= 18.2 - Authenticated Settings Change leading to Arbitrary File Upload
Critical 9.9
In plain English
A critical-severity missing authorization in Frontend File Manager Plugin from nmedia. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.9% (higher than 79% of all known vulnerabilities).
Official 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.
