The The WP Popup Builder – Popup Forms and Marketing Lead Generation plugin for WordPress is vulnerable to arbitrary shortcode execution via the wpajaxnoprivshortcodeApiAdd AJAX action in all versions up to, and including, 1.3.5. This is due to the software allowing users to execute an action that does not properly validate a value before running doshortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. NOTE: This vulnerability was partially fixed in version 1.3.5 with a nonce check, which effectively prevented access to the affected function. However, version 1.3.6 incorporates the correct authorization check to prevent unauthorized access.
