NVD Description

Note: Versions mentioned in the description apply only to the upstream n8n-oci-entrypoint package and not the n8n-oci-entrypoint package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

n8n before 2.25.7 and 2.26.x before 2.26.2 contains an abstract syntax tree (AST) security validator bypass in the Python Code node. An authenticated user with permission to create or modify workflows containing a Python Code node can bypass the validator and access the task executor module namespace. The issue only affects self-hosted instances where the Python Task Runner is enabled; where N8N_BLOCK_RUNNER_ENV_ACCESS is configured to allow it, this can disclose environment variables accessible to the task runner process.
