Overview
Affected versions of this package are vulnerable to Improper Authorization in the structure_data endpoint, which returns external dependency graph nodes for linked DAGs without verifying whether the caller has read permission for those DAGs. An attacker can access metadata and enumerate linked DAG IDs for which they do not have authorization by making authenticated UI or API requests.
