      "value": "Apache Airflow's secrets masker did not mask `var.json` Variable values whose value is a dict in the Rendered Templates UI — the dict value failed an `isinstance(str)` guard — so a secret stored as a JSON Variable and referenced in a template via `var.json` was displayed in cleartext to any user with access to that task's Rendered Templates view. Users are advised to upgrade to apache-airflow 3.3.1 or later, which masks nested Variable values regardless of type."

      "value": "El enmascarador de secretos de Apache Airflow no enmascaró los valores de la Variable ’var.json’ cuyo valor es un diccionario en la interfaz de usuario de Plantillas Renderizadas - el valor del diccionario falló una comprobación ’isinstance(str)’ - por lo que un secreto almacenado como una Variable JSON y referenciado en una plantilla a través de ’var.json’ se mostró en texto claro a cualquier usuario con acceso a la vista de Plantillas Renderizadas de esa tarea. Se aconseja a los usuarios actualizar a apache-airflow 3.3.1 o posterior, que enmascara los valores de Variables anidadas independientemente del tipo."
