{"schema_version": "1.6.1", "id": "CVE-2026-40963", "summary": "DAG authorization bypass on /ui/structure/structure_data", "details": "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "3.0.0"}, {"fixed": "3.2.2"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/65342"}, {"type": "WEB", "url": "https://lists.apache.org/thread/s907bhsksc37m59f0loqjcp1ryobrr60"}]}
