GHSA-fpxx-xv4c-gxqp: Apache Airflow vulnerable to sensitive information exposure when expose-config is set to non-sensitive-only

Apache Airflow, versions 2.7.0 and 2.7.1, is affected by a vulnerability that allows an authenticated user to retrieve sensitive configuration information when the "expose_config" option is set to "non-sensitive-only". The `expose_config` option is False by default. It is recommended to upgrade to a version that is not affected.
