SureCart version prior to 4.2.1 are vulnerable to authenticated SQL injection via multiple parameters ('modelname', 'modelid', 'integrationid', '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.

The SureCart plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 4.2.3. This is due to the plugin not properly validating a user's identity prior to updating their details like email during customer profile synchronization from webhook events. This makes it possible for unauthenticated attackers to change linked user's email addresses, including administrators if the administrator account is linked to a SureCart customer record, and leverage that to reset the user's password and gain access to their account if the customer ID is known.
