Description
The MDirector Newsletter plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.5.8. This is due to missing nonce verification on the mdirectorNewsletterSave function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
