CVE-2026-40963

3.1 lowEPSS 0.5%

Low (3.1) in apache airflow. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in apache-airflow 3.2.2.

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.
