Vulnerability Title
n8n - SQL Injection in MySQL v1 executeQuery Operation via Expression Interpolation
Vulnerability Description
n8n before 1.123.61, 2.x before 2.27.4, and 2.28.x before 2.28.1 contains a SQL injection vulnerability in the legacy MySQL v1 node's executeQuery operation. The operation substitutes evaluated {{ ... }} expression values directly into the raw SQL string without parameterization. When a workflow uses this operation with expression-sourced values and is connected to an externally-reachable trigger (such as a Webhook node), attacker-controlled input reaching those expressions results in SQL injection, allowing execution of arbitrary SQL with the configured MySQL credentials' privileges. The MySQL v2 node, which uses parameterized queries, is not affected.

Vulnerability Title
n8n SQL注入漏洞
Vulnerability Description
n8n是n8n公司开源的一个可扩展的工作流自动化工具。 n8n存在SQL注入漏洞,该漏洞源于legacy MySQL v1节点executeQuery操作中未对表达式值进行参数化,直接将评估后的{{ ... }}表达式值替换到原始SQL字符串中,当工作流使用此操作并连接外部可访问触发器(如Webhook节点)时,攻击者控制的输入可导致SQL注入,从而使用配置的MySQL凭据权限执行任意SQL。以下版本受到影响:1.123.61之前版本、2.27.4之前版本和2.28.1之前版本。
