HashBar – Announcement, Notification Bar & Popup Campaign < 2.0.1 - Cross-Site Request Forgery

Description

The HashBar – Announcement, Notification Bar & Popup Campaign plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
