Affected versions
| Package | Affected | Fixed in |
|---|---|---|
| apache-airflow PyPI | >= 3.0.0, < 3.2.2 | 3.2.2 |
Details and references
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.
