AI-suggested

Upgrade Apache Airflow to version 3.4.0 or later, where this issue has been fixed. No other mitigation is indicated by the vendor advisory.

Description

Apache Airflow versions prior to 3.4.0 have a vulnerability in the asset API endpoints where authenticated users with asset read access can obtain IDs of Dags they are not authorized to view. This exposure occurs because the API does not verify if the caller has permission to read those Dags. The issue is fixed in version 3.4.0.
