      "value": "A bug in Apache Airflow's bulk Task Instances API (`PATCH/DELETE /api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances`) evaluated authorization against the `dag_id` resolved from the URL path while operating on the `dag_id` / `dag_run_id` extracted from request-body entity fields. An authenticated UI/API user with edit permission on one Dag could mutate Task Instance state in any other Dag by keeping the authorized Dag's ID in the URL path and naming the target Dag's IDs in the request body entities. Affects deployments that rely on per-Dag edit-scope to keep Task Instance state isolated between teams. Users are advised to upgrade to `apache-airflow` 3.2.2 or later."

      "value": "Un error en la API de instancias de tareas masivas de Apache Airflow (PATCH/DELETE /api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances) evaluaba la autorización contra el 'dag_id' resuelto de la ruta URL mientras operaba sobre el 'dag_id' / 'dag_run_id' extraído de los campos de entidad del cuerpo de la solicitud. Un usuario de UI/API autenticado con permiso de edición en un Dag podía mutar el estado de la instancia de tarea en cualquier otro Dag manteniendo el ID del Dag autorizado en la ruta URL y nombrando los IDs de los Dags objetivo en las entidades del cuerpo de la solicitud. Afecta a las implementaciones que dependen del alcance de edición por Dag para mantener el estado de la instancia de tarea aislado entre equipos. Se aconseja a los usuarios actualizar a 'apache-airflow' 3.2.2 o posterior."
