CVE-2026-27498— n8n 代码注入漏洞

n8n has Arbitrary Command Execution via File Write and Git Operations

n8n is an open source workflow automation platform. Prior to versions 2.2.0 and 1.123.8, an authenticated user with permission to create or modify workflows could chain the Read/Write Files from Disk node with git operations to achieve remote code execution. By writing to specific configuration files and then triggering a git operation, the attacker could execute arbitrary shell commands on the n8n host. The issue has been fixed in n8n versions 2.2.0 and 1.123.8. Users should upgrade to one of these versions or later to remediate the vulnerability. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only, and/or disable the Read/Write Files from Disk node by adding `n8n-nodes-base.readWriteFile` to the `NODES_EXCLUDE` environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

n8n 代码注入漏洞

n8n是n8n开源的一个可扩展的工作流自动化工具。 n8n 2.2.0之前版本和1.123.8之前版本存在代码注入漏洞，该漏洞源于具有权限的认证用户可链式利用Read/Write Files from Disk节点与git操作，可能导致远程代码执行。
