[Ephraim Anierobi <ephraimanierobi () apache org>]

Severity: low

Affected versions:

- Apache Airflow before 2.7.2

Description:

Apache Airflow, versions prior to 2.7.2, contains a security vulnerability that allows authenticated users of Airflow 
to list warnings for all DAGs, even if the user had no permission to see those DAGs. It would reveal the dag_ids and 
the stack-traces of import errors for those DAGs with import errors.
Users of Apache Airflow are advised to upgrade to version 2.7.2 or newer to mitigate the risk associated with this 
vulnerability.
