CVE-2026-42229— n8n: SQL Injection in SeaTable Node

Quick assessment

Affected
n8n-io n8n
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.

n8n是n8n开源的一个可扩展的工作流自动化工具。 n8n 1.123.32之前版本、2.17.4之前版本和2.18.1之前版本存在SQL注入漏洞，该漏洞源于SeaTable节点的row:search和row:get操作中用户控制输入直接拼接至SQL查询字符串而未进行转义或参数化，可能导致攻击者操纵查询以检索SeaTable基中非预期行，绕过工作流中实现的行级过滤逻辑。

Vulnerability Title
n8n: SQL Injection in SeaTable Node
Source: CVE Program / CVE List V5
Vulnerability Description
n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the SeaTable node's row:search and row:get operations allowed user-controlled input to be concatenated directly into SQL query strings without escaping or parameterization. In workflows where external user input is passed via expressions into the SeaTable node's search or row retrieval parameters, an attacker could manipulate the constructed query to retrieve unintended rows from the connected SeaTable base, bypassing row-level filtering logic implemented in the workflow. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.
