Asgaros Forum < 2.9.0 - Cross-Site Request Forgery

Description

The Asgaros Forum plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.8.0. This is due to missing or incorrect nonce validation on the mark_all_read() function. This makes it possible for unauthenticated attackers to mark post topics as read via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
