Severity: low 

Affected versions:

- Apache Airflow (apache-airflow) 3.1.0 before 3.1.7

Description:

Apache Airflow versions 3.1.0 through 3.1.6 contain an authorization flaw that can allow an authenticated user with

Users are recommended to upgrade to Apache Airflow 3.1.7 or later, which resolves this issue.
