    Am I affected by n8n: Python sandbox escape? What should I do?

    An authenticated user with permission to create or modify workflows containing a Python Code Node could escape the sandbox.

      Am I affected? Affected: n8n < 1.123.48, 2.0.0-rc.0 to 2.21.8, and 2.22.0 to 2.22.4. Fixed in: 1.123.48.

      • Check your version: run npm ls n8n. Versions < 1.123.48 of n8n are affected.

      What to do now

      1. Upgrade to the fixed version: run npm install n8n@1.123.48 (first patched version 1.123.48).
      2. Upgrade to n8n 1.123.48, 2.21.8, or 2.22.4, or later.
      3. Limit workflow creation and editing permissions to fully trusted users only.
      4. Disable the Python Code node by adding n8n-nodes-base.code to the NODES_EXCLUDE environment variable, or disable the Python Task Runner entirely.

      General practice, not from the source: if the affected software could read tokens or credentials, rotate them after upgrading; pin versions and review changes before updating tools your agents run.
