Cross site request forgery (csrf)

The YourChannel plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.3. This is due to missing or incorrect nonce validation on the saveLang function. This makes it possible for unauthenticated attackers to change the plugin’s quick language translation settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
