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.\n\n## Affected packages\n\n- `apache-airflow >= 3.0.0, < 3.2.2`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `apache-airflow 3.2.2`","depth":"sunlit","depthScore":17,"depthScoreParts":{"impact":17.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
