Apache Airflow: per-DAG RBAC bypass on /ui/partitioned_dag_runs endpoints
The partitioned_dag_runs endpoints in the Airflow UI enforced only asset-level access control, not per-Dag authorization. An authenticated UI/API user with global Asset:read permission could enumerate partition run state, schedule configuration, and asset wiring for Dags they were not authorized to read. Affects deployments that rely on per-Dag read scoping while granting users broader Asset access. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.
