An authenticated user with permission to create or modify workflows containing a Python Code Node could escape the sandbox and achieve arbitrary code execution on the task runner container.
This issue only affects instances where the Python Task Runner is enabled.
The issue has been fixed in n8n versions 1.123.48, 2.21.8, and 2.22.4. 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:
n8n-nodes-base.code to the NODES_EXCLUDE environment variable, or disable the Python Task Runner entirely.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
n8n < 1.123.48n8n >= 2.22.0, < 2.22.4n8n >= 2.0.0-rc.0, < 2.21.8Upgrade to a patched release:
