n8n is an open source workflow automation platform. Prior to version 2.4.8, 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. This issue has been patched in version 2.4.8.

GHSA-8398-gmmx-564h — n8n has a Python sandbox escape

2026-10-03T09:43:14.119809+00:00

Affected: npm: n8n

## 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 following conditions were met:

- Task Runners were enabled using `N8N_RUNNERS_ENABLED=true` (default: false) - Python was enabled `N8N_PYTHON_ENABLED=true` - Code Node was enabled (default: true)

In case the `N8N_RUNNERS_MODE` is set to `external` (default: `internal`) the sandbox escape is limited to the sidecar container with lower risk for lateral movement. In that case a lower high severity is more appropriate.

## Patches

This vulnerability is fixed in version 2.4.8 and later.

## Workarounds

If an immediate upgrade cannot be applied, the following hardening steps are recommended:

- Disable the Code Node by adding `n8n-nodes-base.code` to the `NODES_EXCLUDE` environment variable - Prefer external mode for isolation: run Task Runners in external mode so that untrusted task code executes in a separate sidecar container rather than within the main n8n process. This configuration significantly reduces the risk of in-process memory disclosure caused by unsafe buffer [allocations.In](http://allocations.in/) external mode, a launcher manages Task Runner processes in a dedicated sidecar environment, separate from the primary n8n instance.

WID-SEC-W-2026-0318 — n8n: Mehrere Schwachstellen

2026-10-03T09:43:14.119887+00:00

Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in n8n ausnutzen, um beliebigen Code auszuführen, sich erhöhte Berechtigungen zu verschaffen, Cross-Site-Scripting-Angriffe durchzuführen und vertrauliche Informationen offenzulegen. Über einige dieser Schwachstellen sind weitere Angriffe möglich, wie beispielsweise die Übernahme von Konten, das Hijacking von Sitzungen und die vollständige Kompromittierung des Systems.
