Severity Rating: CRITICAL

Software Affected

  • n8n Workflow Automation Platform (npm) versions prior to 2.0.0

Overview

A critical vulnerability has been reported in n8n Workflow Automation Platform (npm), which could be exploited by an authenticated attacker to execute arbitrary code, perform a sandbox escape, and gain unauthorized access on the targeted system.

Target Audience:
System administrators, DevOps teams and organizations deploying or managing n8n Workflow Automation Platform.

Risk Assessment:
High risk of arbitrary code execution, sandbox escape, and unauthorized access.

Impact Assessment:
Potential for full system compromise, sensitive data exposure, workflow manipulation, service disruption, and unauthorized lateral movement.

Description

n8n is an open-source workflow automation platform used to design, execute and manage automated workflows that integrate applications, services and APIs.

A critical vulnerability exists in the n8n Python Code Node due to sandbox bypass flaw. This vulnerability could be exploited by an authenticated user with permission to create or modify workflows.

Workaround

  • Disable Code Node: Set the value for environment variable NODES_EXCLUDE to "["n8n-nodes-base.code"]" 
  • Disable python support in Code Node: Set environment variable N8N_PYTHON_ENABLED as false. 
  • Use environment variables N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER to use task runner based python sandbox.
