The Disable Admin Notices – Hide Dashboard Notifications plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.2. This is due to missing nonce validation in the showPageContent() function. This makes it possible for unauthenticated attackers to add arbitrary URLs to the blocked redirects list via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
