Vulnerability Title
n8n - Arbitrary File Read and Execution via ExecuteWorkflow localFile Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
n8n before 2.19.3 contains a file path restriction bypass in the legacy ExecuteWorkflow node's localFile source option, which reads workflow files from disk without the file-access checks enforced by other file-reading nodes. Although hidden from the UI since v1.2, it remains reachable via the REST API. An authenticated user with permission to create or modify workflows can supply an arbitrary file path to bypass the N8N_RESTRICT_FILE_ACCESS_TO restriction and determine whether arbitrary files exist on the host; where the targeted path contains a valid workflow JSON file, that file can additionally be loaded and executed.

n8n 路径遍历漏洞

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 2.19.3之前版本存在路径遍历漏洞，该漏洞源于旧ExecuteWorkflow节点的localFile source选项存在文件路径限制绕过问题，它从磁盘读取工作流文件时没有其他文件读取节点强制执行的访问检查。尽管自v1.2起用户界面已隐藏此选项，但仍可通过REST API访问。经过身份验证并拥有创建或修改工作流权限的用户可以提供任意文件路径来绕过N8N_RESTRICT_FILE_ACCESS_TO限制，从而确认主机上是否存在任意文件；若
