Media Library Helper by Codexin <= 1.2.0 - Cross-Site Request Forgery via rate_the_plugin_action

The Media Library Helper by Codexin plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.0. This is due to missing or incorrect nonce validation on the rate_the_plugin_action function. This makes it possible for unauthenticated attackers to dismiss the plugin rating via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
