Input validation vulnerability in Hello Elementor 3.0.0

The Hello Elementor theme for WordPress has a weakness that puts it at risk for Cross-Site Request Forgery. This means that versions up to and including 3.0.0 are vulnerable. The problem lies in the way the ajax_hello_elementor_set_admin_notice_viewed() function handles nonces, which are important security measures. As a result, attackers without authorization can make it seem like a site administrator has dismissed a notice by tricking them into taking an action, like clicking on a link.
