CVE-2026-40963
Full vulnerability record from the local CVENow database.
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.

"value": "El endpoint 'structure_data' en la interfaz de usuario (UI) de Airflow devolvió nodos de grafo de dependencia externa para DAGs vinculados sin verificar si el llamador tenía permiso de lectura sobre esos DAGs vinculados. Un usuario autenticado de la UI/API autorizado para un DAG podría enumerar IDs de DAGs vinculados y metadatos de dependencia para otros DAGs que no estaba autorizado a leer. Afecta a las implementaciones que dependen del alcance de lectura por DAG para mantener privada la topología de dependencia de DAG entre equipos. Se aconseja a los usuarios actualizar a apache-airflow 3.2.2 o posterior."
