Update, patch or deactivate.
Update Surecart to 4.2.1 or later, or disable and remove it until a fixed version is available.
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
SureCart version prior to 4.2.1 are vulnerable to authenticated SQL injection via multiple parameters ('model_name', 'model_id', 'integration_id', 'provider') on the REST API endpoint '/surecart/v1/integrations/{id}'. The root cause is a flawed escaping bypass in the query builder ('wp-query-builder'). Values passed to the 'where()' method are only sanitized via '$wpdb->prepare()' when they do **not** contain a dot ('.') or the WordPress table prefix ('wp_'). By including a dot anywhere in the payload, an attacker completely bypasses the escaping logic and injects arbitrary SQL into the 'WHERE' clause, allowing full UNION-based extraction of the database.
