CVE-2026-28563: Apache Airflow: DAG authorization bypass

[Rahul Vats <rahulvats () apache org>]

Severity: low 

Affected versions:

- Apache Airflow (apache-airflow) 3.0.0 before 3.1.8

Description:

Apache Airflow versions 3.1.0 through 3.1.7 /ui/dependencies endpoint returns the full DAG dependency graph without 
filtering by authorized DAG IDs. This allows an authenticated user with only DAG Dependencies permission to enumerate 
DAGs they are not authorized to view.


Users are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue.
