The Lead Form Data Collection to CRM plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several functions in the ~/includes/LB_admin_ajax.php file in all versions up to, and including, 3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform several actions like updating settings. Initially this CVE was assigned specifically to all AJAX actions and the doFieldAjaxAction() function, however it was determined that CVE-2025-47690 is assigned to the doFieldAjaxAction() function that leads to arbitrary options updates.

The Lead Form Data Collection to CRM plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the doFieldAjaxAction() function in all versions up to, and including, 3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site. Other AJAX actions handling plugin settings are also insufficiently protected and exploitable.
