Grand Restaurant WordPress <= 7.0 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Grand Restaurant WordPress theme for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.
