CVE-2026-104724: FireBox <= 3.1.13 - Authenticated (Author+) SQL Injection via FireBox Form Display Condition
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 makes it possible for 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 editfireboxes capability to any role that previously held editposts, reducing the minimum required privilege to Author-level.

Event History
Frequently Asked Questions
Are newly installed sites exposed to author-level exploitation?
No. On fresh installations of version 3.1.10 and later, exploitation requires administrator-level access. The lower Author-level requirement applies to sites upgraded from versions earlier than 3.1.10.
Why do upgraded installations have a lower privilege threshold?
During upgrades from versions before 3.1.10, the preserveCampaignRoleAccess() migration grants the edit_fireboxes capability to roles that previously had edit_posts. This can allow Author-level users to meet the capability requirement.
What could an attacker obtain through successful exploitation?
An authenticated attacker able to exploit the condition can append SQL to existing queries and extract sensitive information from the WordPress database. The vulnerability affects confidentiality; no integrity or availability impact is stated.
