Customizr < 4.4.22 - Cross-Site Request Forgery to Notice Dismissal

Description

The Customizr theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.4.21. This is due to missing or incorrect nonce validation. 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.
