The RAYS Grid plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.2. This is due to missing or incorrect nonce validation on the rsgd_insert_update() function. This makes it possible for unauthenticated attackers to update post fields via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
