Description

The Popup Box – Create Countdown, Coupon, Video, Contact Form Popups plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.0.7. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.
