CVE-2026-40963
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk37th percentile - higher than 37% of all known CVEs
Summary
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.
Risk Assessment
Organizations relying on per-DAG read scoping to keep DAG dependency topology private across teams are at risk of information disclosure about DAG structure.
Recommendation
Users are advised to upgrade to `apache-airflow` 3.2.2 or later.
