Fontific | Google Fonts <= 0.1.6 - Cross-Site Request Forgery via ajax_fontific_save_all

Description The Fontific | Google Fonts plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.1.6. This is due to missing or incorrect nonce validation on the ‘ajax_fontific_save_all’ function. This makes it possible for unauthenticated attackers to modify the plugin’s settings, which includes injecting malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
