Font Pairing Preview For Landing Pages <= 1.3 - Cross-Site Request Forgery to Settings Update

The Font Pairing Preview For Landing Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3. This is due to missing nonce validation on the settings update functionality. This makes it possible for unauthenticated attackers to modify the plugin's font pairing settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
