At a glance
CVE-2026-104724 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the FireBox WordPress plugin, affecting versions <= 3.1.13. It carries a CVSS score of 5.3 (reachable over the network; high confidentiality impact). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 3.1.14; sites on affected versions should update now. Disclosed October 2026, reported by Wordfence PRISM.
Vulnerability Overview
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 edit_fireboxes capability to any role that previously held edit_posts, reducing the minimum required privilege to Author-level.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
FireBox <= 3.1.13 carries this weakness at preserveCampaignRoleAccess(), and reaching it takes an account at Author level or above. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For FireBox the fix is 3.1.14: builds <= 3.1.13 are affected, anything from 3.1.14 onward is not.
Remediation
Update to version 3.1.14, or a newer patched version
How does WordSec protect against this?
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: FireBox 3.1.14 closes this, and updating the plugin is the step that ends it.
