Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Limit workflow creation and editing permissions to fully trusted users only.\n- Disable the Python Code node by adding `n8n-nodes-base.code` to the `NODES_EXCLUDE` environment variable, or disable the Python Task Runner entirely.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.\n\n## Affected packages\n\n- `n8n < 1.123.48`\n- `n8n >= 2.22.0, < 2.22.4`\n- `n8n >= 2.0.0-rc.0, < 2.21.8`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `n8n 1.123.48`\n- `n8n 2.22.4`\n- `n8n 2.21.8`","depth":"twilight","depthScore":47,"depthScoreParts":{"impact":46.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
