FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment: SQL injection
An Author can reach SQL injection in FormDisplayCondition on sites that retained an older Campaign Role Access grant of edit_fireboxes to edit_posts users. Fresh installations from 3.1.10 use Administrator-only access, so the lower-privilege path depends on preserved configuration. The export does not name the injected parameter. Affected versions: <= 3.1.13.

Update, patch or deactivate.
The official author release notes confirm remediation by 3.1.14; this does not establish that every intervening release was affected. Update the affected edition to 3.1.14 or a later maintained release on its supported branch. Disable the affected feature or deactivate the component until the update is installed. Application-level remediation: Parameterize values used by the submitted-form display condition, allowlist query identifiers, and enforce the intended campaign-management capability.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
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.
