Input validation vulnerability in EmpowerWP 1.0.21

The EmpowerWP theme for WordPress has a security issue that could potentially be exploited by attackers. This vulnerability affects versions 1.0.21 and below. The issue is related to a function called empower_admin_ajax_welcome_notice_dismiss, which does not properly check for a security code. This means that if a site administrator is tricked into clicking on a link, an attacker could use a fake request to dismiss a notice without proper authorization.
