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

Quick assessment

Affected
ntbyk JTL-Connector for WooCommerce
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的 JTL-Connector for WooCommerce 插件在 2.4.3 及更早版本中存在基于时间的 SQL 注入漏洞，该漏洞存在于 'product.push' 身份端点中。此漏洞是由于对用户提供的参数未进行充分转义，且对现有 SQL 查询未执行足够的预处理所致。攻击者无需认证即可利用此漏洞，向已有查询中追加额外的 SQL 查询，从而从数据库中提取敏感信息。该注入发生在身份链接阶段，早于 ProductController::push() 方法的执行，因此即使下游的产品处理逻辑本应拒

Vulnerability Title
JTL-Connector for WooCommerce <= 2.4.3 - Unauthenticated SQL Injection
Source: CVE Program / CVE List V5
Vulnerability Description
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.
