A user with limited feature privileges can access workflow execution outputs in their Kibana space without the authorization required to do so through the documented API. The accessible data may include sensitive information returned by workflow steps, such as results from connected data sources that the caller would not otherwise be authorized to access."

Un usuario con privilegios de funciones limitados puede acceder a las salidas de ejecución de flujos de trabajo en su espacio de Kibana sin la autorización requerida para hacerlo a través de la API documentada. Los datos accesibles pueden incluir información sensible devuelta por los pasos del flujo de trabajo, como resultados de fuentes de datos conectadas a las que el llamador no estaría autorizado a acceder de otro modo."
