Background

Apache Airflow is an open-source platform used for orchestrating and scheduling workflows. It allows users to define, schedule, and monitor complex workflows as Directed Acyclic Graphs (DAGs). This vulnerability affects versions prior to 2.7.2 of Apache Airflow.

Vulnerability Detail

The vulnerability in Apache Airflow allows authenticated users to list warnings for all DAGs, even if they do not have permission to view those DAGs. This exposes the dag_ids and stack traces of import errors for DAGs with import errors. An attacker with access to this information may gain insights into the structure and potential vulnerabilities of the affected DAGs.
