Starter Templates — Elementor, WordPress & Beaver Builder Templates <= 3.1.20 - Cross-Site Request Forgery in add_to_favorite

The Starter Templates — Elementor, WordPress & Beaver Builder Templates plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.1.20. This is due to missing or incorrect nonce validation on the add_to_favorite function. This makes it possible for unauthenticated attackers to set a Starter Template as favorite via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
