AI description

Automated description summarized from trusted sources.

CVE-2025-68668 is a vulnerability that affects n8n, an open-source workflow automation platform. Specifically, it is a sandbox bypass vulnerability found in the Python Code Node that utilizes Pyodide. This vulnerability exists in n8n versions from 1.0.0 to before 2.0.0. An authenticated user with the permission to create or modify workflows can exploit this vulnerability to execute arbitrary commands on the host system running n8n. The attacker can execute commands with the same privileges as the n8n process. This issue has been patched in version 2.0.0. Workarounds include disabling the Code Node or Python support, or configuring n8n to use the task runner-based Python sandbox.

Description: 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 on the host system running n8n, using the same privileges as the n8n process. This issue has been patched in version 2.0.0. Workarounds for this issue involve disabling the Code Node by setting the environment variable NODES_EXCLUDE: "[\"n8n-nodes-base.code\"]", disabling Python support in the Code node by setting the environment variable N8N_PYTHON_ENABLED=false, which was introduced in n8n version 1.104.0, and configuring n8n to use the task runner based Python sandbox via the N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER environment variables.
