Vulnerability Title
n8n before 1.123.64 Remote Code Execution via Git Clone
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.

n8n 竞争条件问题漏洞
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 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。
