Animated Rotating Words <= 5.6 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Dynamic Word Spinner: CSS3 Animated Rotation plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.6. This is due to missing or incorrect nonce validation on the save_admin_options() function. This makes it possible for unauthenticated attackers to update plugin settings granted they can trick a site administrator into performing an action such as clicking on a link.
