OnePress <= 2.3.6 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The OnePress theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.3.6. This is due to missing or incorrect nonce validation on the save_settings() 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.
