CVE-2026-49444
n8n: Python sandbox escape
描述
## Impact 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. ## Patches 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. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Limit workflow creation and editing permissions to fully trusted users only. - Disable the Python Code node by adding `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.
