Rate my Post <= 3.3.4 is vulnerable to Cross-Site Request Forgery (CSRF) vulnerability

The Rate my Post plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.3.4. This is due to missing or incorrect nonce validation on the has_valid_nonce function. This makes it possible for unauthenticated attackers to vote on posts, via forged request granted they can trick a site user into performing an action such as clicking on a link.
