WPCS < 1.2.0.2 - Cross-Site Request Forgery

Description The WPCS plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.0.1. This is due to missing or incorrect nonce validation on the save_etalon() function. This makes it possible for unauthenticated attackers to update the plugin’s settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
