Description

The Custom Fonts – Host Your Fonts Locally plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'BCF_Google_Fonts_Compatibility' class constructor function in all versions up to, and including, 2.1.16. This makes it possible for unauthenticated attackers to delete font directory and rewrite theme.json file.
