      "value": "Before Airflow 3.2.0, it was unclear that secure Airflow deployments require the Deployment Manager to take appropriate actions and pay attention to security details and security model of Airflow. Some assumptions the Deployment Manager could make were not clear or explicit enough, even though Airflow's intentions and security model of Airflow did not suggest different assumptions. The overall security model [1], workload isolation [2], and JWT authentication details [3] are now described in more detail. Users concerned with role isolation and following the Airflow security model of Airflow are advised to upgrade to Airflow 3.2, where several security improvements have been implemented. They should also read and follow the relevant documents to make sure that their deployment is secure enough. It also clarifies that the Deployment Manager is ultimately responsible for securing your Airflow deployment. This had also been communicated via Airflow 3.2.0 Blog announcement [4].\n\n[1] Security Model:  https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html \n[2] Workload isolation:  https://airflow.apache.org/docs/apache-airflow/stable/security/workload.html \n[3] JWT Token authentication:  https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html \n[4] Airflow 3.2.0 Blog announcement:  https://airflow.apache.org/blog/airflow-3.2.0/ \n\n\n\nUsers are recommended to upgrade to version 3.2.0, which fixes this issue."

      "value": "Antes de Airflow 3.2.0, no estaba claro que las implementaciones seguras de Airflow requieren que el Gestor de Implementación tome las acciones apropiadas y preste atención a los detalles de seguridad y al modelo de seguridad de Airflow. Algunas suposiciones que el Gestor de Implementación podría hacer no eran lo suficientemente claras o explícitas, a pesar de que las intenciones de Airflow y el modelo de seguridad de Airflow no sugerían suposiciones diferentes. El modelo de seguridad general [1], el aislamiento de la carga de trabajo [2] y los detalles de autenticación JWT [3] ahora se describen con más detalle. Se aconseja a los usuarios preocupados por el aislamiento de roles y por seguir el modelo de seguridad de Airflow que actualicen a Airflow 3.2, donde se han implementado varias mejoras de seguridad. También deben leer y seguir los documentos relevantes para asegurarse de que su implementación sea lo suficientemente segura. También aclara que el Gestor de Implementación es, en última instancia, responsable de asegurar su implementación de Airflow. Esto también se había comunicado a través del anuncio del blog de Airflow 3.2.0 [4].\n\n[1] Modelo de Seguridad: https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html\n[2] Aislamiento de la carga de trabajo: https://airflow.apache.org/docs/apache-airflow/stable/security/workload.html\n[3] Autenticación de tokens JWT: https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html\n[4] Anuncio del blog de Airflow 3.2.0: https://airflow.apache.org/blog/airflow-3.2.0/\n\nSe recomienda a los usuarios actualizar a la versión 3.2.0, que soluciona este problema."
