Apache Airflow encryption issue vulnerability

Versions of Apache Airflow prior to 7.0.0 contain an encryption vulnerability. This vulnerability arises because code paths such as SFTPTrigger, SFTPHookAsync, and SFTPClientPool are by default disabled from performing SSH host key validation; this behavior is only triggered when the connection...
