CVE-2024-9061 – WP Popup Builder – Popup Forms and Marketing Lead Generation <= 1.3.5 - Unauthenticated Arbitrary Shortcode Execution via wp_ajax_nopriv_shortcode_Api_Add

https://notcve.org/view.php?id=CVE-2024-9061

The The WP Popup Builder – Popup Forms and Marketing Lead Generation plugin for WordPress is vulnerable to arbitrary shortcode execution via the wp_ajax_nopriv_shortcode_Api_Add 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 do_shortcode. 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. • https://github.com/RandomRobbieBF/CVE-2024-9061 https://plugins.trac.wordpress.org/changeset/3166506/wp-popup-builder https://www.wordfence.com/threat-intel/vulnerabilities/id/0cac1dc0-87dc-43eb-9db1-638a91200b43?source=cve • CWE-94: Improper Control of Generation of Code ('Code Injection') •
