Setka Editor <= 2.1.20 - Cross-Site Request Forgery via handleRequest

Description The A no-code page builder for beautiful performance-based content plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.20. This is due to missing or incorrect nonce validation on the ‘handleRequest’ function. This makes it possible for unauthenticated attackers to dismiss admin notices via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
