      "value": "The Elasticsearch logging provider, when configured with a `host` URL that embeds credentials (for example `https://user:[email protected]:9200`), wrote the full host URL — including the embedded credentials — into task logs. Any user with task-log read permission could harvest the backend credentials. Users are advised to upgrade to `apache-airflow-providers-elasticsearch` 6.5.3 or later and, as a defense-in-depth measure, configure the backend credentials via a secret backend rather than embedding them in the `[elasticsearch] host` URL."

      "value": "El proveedor de registro de Elasticsearch, cuando se configuraba con una URL de ’host’ que incrusta credenciales (por ejemplo, ’https://user:[email protected]:9200’), escribía la URL completa del ’host’ -incluyendo las credenciales incrustadas- en los registros de tareas. Cualquier usuario con permiso de lectura de registros de tareas podía recolectar las credenciales del backend. Se aconseja a los usuarios actualizar a ’apache-airflow-providers-elasticsearch’ 6.5.3 o posterior y, como medida de defensa en profundidad, configurar las credenciales del backend a través de un backend de secretos en lugar de incrustarlas en la URL de ’[elasticsearch] host’."
