RCE AI / ML N8n

Description

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.

Analysis

Remote code execution in n8n workflow automation platform allows authenticated users with workflow creation or modification permissions to execute arbitrary shell commands by chaining file write operations with git functions to manipulate configuration files. Versions prior to 2.2.0 and 1.123.8 are affected, and administrators should upgrade immediately or restrict workflow editing permissions to trusted users only.

Remediation

Within 24 hours: Identify all n8n instances and document current versions; assess which workflows have file disk operations combined with git integrations. Within 7 days: Apply vendor patches (versions 2.2.0 or 1.123.8+) to all n8n deployments; restrict workflow modification permissions to trusted administrators only. …
