An authenticated user with permission to create or modify workflows can exploit this vulnerability to execute arbitrary commands on the host system running n8n, using the same privileges as the n8n process. This issue has been patched in version 2.0.0. Workarounds for this issue involve disabling the Code Node by setting the environment variable NODES_EXCLUDE: \"[\\\"n8n-nodes-base.code\\\"]\", disabling Python support in the Code node by setting the environment variable N8N_PYTHON_ENABLED=false, which was introduced in n8n version 1.104.0, and configuring n8n to use the task runner based Python sandbox via the N8N_RUNNERS_ENABLED and N8N_NATIVE_PYTHON_RUNNER environment variables."

Un usuario autenticado con permiso para crear o modificar flujos de trabajo puede explotar esta vulnerabilidad para ejecutar comandos arbitrarios en el sistema anfitri\u00f3n que ejecuta n8n, utilizando los mismos privilegios que el proceso de n8n. Este problema ha sido parcheado en la versi\u00f3n 2.0.0. Las soluciones alternativas para este problema implican deshabilitar el Nodo de C\u00f3digo configurando la variable de entorno NODES_EXCLUDE: \u0027[\\\u201cn8n-nodes-base.code\\\u201d]\u0027, deshabilitar el soporte de Python en el nodo de C\u00f3digo configurando la variable de entorno N8N_PYTHON_ENABLED=false, la cual fue introducida en la versi\u00f3n 1.104.0 de n8n, y configurando n8n para usar el sandbox de Python basado en el ejecutor de tareas a trav\u00e9s de las variables de entorno N8N_RUNNERS_ENABLED y N8N_NATIVE_PYTHON_RUNNER."
