Houzez Property Feed <= 2.4.21 - Cross-Site Request Forgery to Property Feed Export Deletion

The Houzez Property Feed plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.4.21. This is due to missing or incorrect nonce validation on the "deleteexport" action. This makes it possible for unauthenticated attackers to delete property feed exports via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
