Impact

The Custom Fonts – Host Your Fonts Locally WordPress plugin is vulnerable in all versions up to and including 2.1.16 due to a missing capability check in the BCF_Google_Fonts_Compatibility class constructor, which allows any unauthenticated user to trigger font directory deletion and overwrite the theme.json file. This flaw results in loss of font assets, potential corruption of theme settings, and the inability to access the site without manual restoration. The weakness is classified as a missing authorization issue (CWE-862).
