Summary
The JTL-Connector for WooCommerce plugin for WordPress is affected in all versions through 2.4.3. Insufficient escaping and query preparation in the product.push identity endpoint allow SQL injection (CWE-89). An unauthenticated remote attacker can append SQL queries and use time-based responses to extract sensitive database information. The injection fires during identity linking, before later product handling.

Description from the CNA
The JTL-Connector for WooCommerce plugin for WordPress is vulnerable to time-based SQL Injection via 'product.push' Identity Endpoint in all versions up to, and including, 2.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection fires during identity linking, before ProductController::push() executes, meaning exploitation succeeds even if downstream product handling would otherwise reject the request.
