GHSA-8398-GMMX-564H n8n has a Python sandbox escape

Impact A vulnerability in the Python Code node allows authenticated users to break out of the Python sandbox environment and execute code outside the intended security boundary. Only authenticated users are able to execute code through Task Runners. This issue affected any deployment in which the...

n8n's Unsafe Buffer Allocation Allows In-Process Memory Disclosure in Task Runner

Impact The use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the same Node.js process for example, data from prior requests, tasks, secrets, or tokens,...

CVE-2025-68668 n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node

n8n is an open source workflow automation platform. From version 1.0.0 to before 2.0.0, a sandbox bypass vulnerability exists in the Python Code Node that uses Pyodide. An authenticated user with permission to create or modify workflows can exploit this vulnerability to execute arbitrary commands...

GHSA-62R4-HW23-CC8V n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node

Impact A sandbox bypass vulnerability exists in the Python Code Node that uses Pyodide. An authenticated user with permission to create or modify workflows can exploit this vulnerability to execute arbitrary commands on the host system running n8n, using the same privileges as the n8n process...

PT-2025-53606

Name of the Vulnerable Software and Affected Versions n8n versions prior to 2.0.0 Description n8n is a workflow automation platform. In self-hosted instances before version 2.0.0, when the Code node operates in legacy JavaScript execution mode, authenticated users with workflow editing permission...

Remote Code Execution (RCE)

Overview Affected versions of this package are vulnerable to Remote Code Execution RCE due to insufficient isolation in the Python Code Node that uses Pyodide. An authenticated attacker with permissions to create or modify workflows can execute arbitrary commands on the host system by creating or...
