CVE-2026-40690 PUBLISHED

Apache Airflow: Assets graph view bypasses DAG level access control displaying unrelated topologies and all DAGs names to unauthorized users

Assigner: apache
Reserved: 15.04.2026 Published: 24.04.2026 Updated: 24.04.2026

The asset dependency graph did not restrict nodes by the viewer's DAG read permissions: a user with read access to at least one DAG could browse the asset graph for any other asset in the deployment and learn the existence and names of DAGs and assets outside their authorized scope.

Users are recommended to upgrade to version 3.2.1, which fixes this issue.
