Ashe <= 2.233 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Ashe theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.233. This is due to missing or incorrect nonce validation on the ashe_activation_notice() function. This makes it possible for unauthenticated attackers to dismiss notices via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
