Hello Elementor <= 3.0.0 - Cross-Site Request Forgery to Notice Dismissal

The Hello Elementor theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.0.0. This is due to missing or incorrect nonce validation on the ajax_hello_elementor_set_admin_notice_viewed() function. This makes it possible for unauthenticated attackers to dismiss a notice via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
