Summary

The VR Calendar plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.4.7. This is due to missing or incorrect nonce validation on the syncCalendar() function. This makes it possible for unauthenticated attackers to trigger a calendar sync via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
