Apache Airflow has an Improper Authorization issue

Quick fix

PYSEC-2026-2349 — apache-airflow: upgrade to the fixed version with the command below.

pip install --upgrade 'apache-airflow>=3.2.2'

Details

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.
