What is CVE-2024-9061?

The WP Popup Builder plugin for WordPress is susceptible to arbitrary shortcode execution due to insufficient validation in the wp_ajax_nopriv_shortcode_Api_Add AJAX action. This vulnerability affects all versions prior to 1.3.6, allowing unauthenticated attackers to run arbitrary shortcodes, compromising site integrity and security.
