Apache Airflow: DAG authorization bypass on /ui/structure/structure_data

Published: 6/5/2026Modified: 6/5/2026
Also known as:BIT-airflow-2026-40963

Description

The structure_data endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other Dags they were not authorized to read. Affects deployments that rely on per-Dag read scoping to keep Dag dependency topology private across teams. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.
