CVE-2026-104724

The FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment plugin for WordPress is vulnerable to generic SQL Injection via FireBox Form Display Condition in all versions up to and including 3.1.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This allows authenticated attackers with author-level access and above to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. On fresh installations of version 3.1.10 and later, exploitation requires administrator-level access; however, on sites upgraded from a version prior to 3.1.10, the preserveCampaignRoleAccess() migration grants the edit_fireboxes capability to any role that previously held edit_posts, reducing the minimum required privilege to Author-level.

The risk includes the possibility of extracting sensitive data from the database, such as user data, passwords, or payment information, which could lead to privacy breaches and serious legal consequences. The attack can be performed by authenticated users with author-level access or higher, depending on configuration.

Immediately update the FireBox plugin to the latest patched version. Also restrict author and higher privileges and regularly audit roles and permissions, especially after updates.
