CVE-2026-65598— n8n before 1.123.64 Remote Code Execution via Git Clone

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公司开源的一个可扩展的工作流自动化工具。 n8n 1.123.64版本之前、2.29.8版本和2.30.1版本之前存在竞争条件问题漏洞，该漏洞源于Git节点克隆操作中的TOCTOU竞争条件，允许经过身份验证的攻击者在路径验证后、克隆运行前将目录替换为符号链接，从而绕过路径限制，在社区节点目录植入特制仓库，导致重启后n8n将其作为自定义节点加载，在服务器上执行任意JavaScript。

Vulnerability Title
n8n before 1.123.64 Remote Code Execution via Git Clone
Source: CVE Program / CVE List V5
Vulnerability Description
n8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allows authenticated users to bypass path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This lets an attacker plant a crafted repository in the community node directory, which n8n loads as a custom node on the next restart, executing arbitrary JavaScript on the server. Both self-hosted and cloud instances are affected.
