GiveWP <= 4.15.3 - Cross-Site Request Forgery

The GiveWP plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.15.3 This is due to missing nonce validation on the give_set_notification_status_handler() function. This makes it possible for unauthenticated attackers to disable donation email notifications via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
