301 Redirects - Easy Redirect Manager <= 2.72 - Cross-Site Request Forgery via dismiss_notice

The 301 Redirects - Easy Redirect Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.73. This is due to missing or incorrect nonce validation on the 'dismiss_notice' function. This makes it possible for unauthenticated attackers to dismiss the plugin's admin notifications via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
