      "value": "Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI. Masking was applied only when the deserialized value was a string or a dict; a list at the top level matched neither and was returned unmasked. Any authenticated user able to read the logs or rendered templates of a task that references such a Variable could recover the values, with no special configuration required. This is the list-shaped counterpart of CVE-2026-59244, whose fix covered the dict case only, so deployments that upgraded in response to that advisory remain affected and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later."

      "value": "El SDK de Tareas de Apache Airflow no enmascaraba el contenido de una Variable cuyo valor JSON es una lista, por lo que los secretos almacenados con esa forma aparecían en texto claro en los registros de tareas y en la interfaz de usuario de Plantillas Renderizadas. El enmascaramiento se aplicaba solo cuando el valor deserializado era una cadena o un diccionario; una lista en el nivel superior no coincidía con ninguno de ellos y se devolvía sin enmascarar. Cualquier usuario autenticado capaz de leer los registros o las plantillas renderizadas de una tarea que hace referencia a dicha Variable podía recuperar los valores, sin necesidad de configuración especial. Esta es la contraparte con forma de lista de CVE-2026-59244, cuya corrección cubría solo el caso del diccionario, por lo que las implementaciones que se actualizaron en respuesta a ese aviso siguen afectadas y deben actualizarse de nuevo. Se aconseja a los usuarios que actualicen a apache-airflow 3.3.1 o posterior."
