Description

The WPCal.io – Easy Meeting Scheduler plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.9.5.8.

This makes it possible for unauthenticated attackers to perform a variety of unauthorized actions granted they can trick a site administrator into performing an action such as clicking on a link.
