Upgrade apache-airflow-providers-sftp to version 7.0.0 or higher.
Overview
apache-airflow-providers-sftp is a Provider package apache-airflow-providers-sftp for Apache Airflow
Affected versions of this package are vulnerable to Key Exchange without Entity Authentication via the no_host_key_check default in SSHHook, SSHHookAsync, and SFTPHookAsync, which defaulted to True, causing SSH host key verification to be skipped for any connection that did not explicitly configure it. An attacker positioned between the Airflow worker and the target SSH/SFTP server can intercept or manipulate the connection without detection, enabling a MitM attack against all affected hook types.
Note: This is only exploitable when host_key is not configured and no_host_key_check is not explicitly set to False in the connection extras.
