      "value": "Flowise is a drag-and-drop user interface for building customized large language model (LLM) flows. Prior to 3.1.3, Flowise injects $vars into the code execution sandbox without requiring variables:view, bypassing the permission-protected Variables API. Variables for the active workspace are fetched at packages/components/src/utils.ts and runtime variables are resolved from server environment variables, while the official variables route enforces variables:view. A user or API key that is denied variables:view can call /api/v1/node-custom-function and receive $vars pre-populated with all variables for the workspace, including Variable.name to Variable.value static variables and Variable.name to process.env[Variable.name] runtime variables. This can expose secrets such as database passwords, JWT secrets, SMTP passwords, and cloud keys, depending on the workspace Variables configuration. This issue is fixed in version 3.1.3."

      "value": "Flowise es una interfaz de usuario de arrastrar y soltar para construir flujos personalizados de modelos de lenguaje grandes (LLM). Antes de la versión 3.1.3, Flowise inyecta $vars en el sandbox de ejecución de código sin requerir variables:view, eludiendo la API de Variables protegida por permisos. Las variables para el espacio de trabajo activo se obtienen en packages/components/src/utils.ts y las variables de tiempo de ejecución se resuelven a partir de las variables de entorno del servidor, mientras que la ruta oficial de variables impone variables:view. Un usuario o clave de API a la que se le deniega variables:view puede llamar a /api/v1/node-custom-function y recibir $vars pre-rellenadas con todas las variables para el espacio de trabajo, incluyendo variables estáticas de Variable.name a Variable.value y variables de tiempo de ejecución de Variable.name a process.env[Variable.name]. Esto puede exponer secretos como contraseñas de base de datos, secretos JWT, contraseñas SMTP y claves de nube, dependiendo de la configuración de Variables del espacio de trabajo. Este problema se corrige en la versión 3.1.3."
