CITS Support svg, webp Media and TTF,OTF File Upload, Use Custom Fonts <= 4.2 - Cross-Site Request Forgery to Font Assignment Deletion

The CITS Support svg, webp Media and TTF,OTF File Upload, Use Custom Fonts plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2. This is due to missing or incorrect nonce validation on the cits_assign_fonts_tab() function. This makes it possible for unauthenticated attackers to delete font assignments via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
