Course Redirects for Learndash Plugin <= 0.4 - Cross-Site Request Forgery

The Course Redirects for Learndash plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.4. This is due to missing nonce validation when processing form submissions on the settings page. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
