CVE-2026-78193: JTL-Connector for WooCommerce <= 2.4.3 - Unauthenticated SQL Injection
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.

Frequently Asked Questions
Who can exploit this issue?
An unauthenticated remote attacker can target the vulnerable endpoint. No account, privileges, or user interaction are required.
Are installations affected even if product processing would reject the request?
Yes. The SQL injection occurs during identity linking before ProductController::push() runs, so downstream product-handling validation does not prevent exploitation.
What could an attacker obtain?
The flaw can be used to append SQL to existing queries and extract sensitive information from the WordPress database. The described technique is time-based SQL injection.
Which plugin versions are affected?
JTL-Connector for WooCommerce versions up to and including 2.4.3 are affected.
