Manage Notification E-mails <= 1.8.2 - Cross-Site Request Forgery to Plugin Options Update

The Manage Notification E-mails plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.8.2. This is due to missing or incorrect nonce validation on the reset_settings function. This makes it possible for unauthenticated attackers to reset the plugin's settings, via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
