CVE-2024-9061
CWE-94Published: October 16, 2024· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
The WP Popup Builder plugin for WordPress fails to properly validate input before executing shortcodes, allowing unauthenticated attackers to execute arbitrary shortcodes. This critical flaw can lead to full site compromise.
No public exploit is known, and it is not in KEV. The vulnerability is remotely exploitable.
Update the plugin to version 1.3.6 or later to ensure proper authorization checks are in place.
Technical Analysis
CVE-2024-9061 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
