No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Apache Airflow FTP provider's FTPSHook.get_conn() created an ftplib.FTP_TLS connection but never called prot_p(), so although the control channel was TLS-protected the data channel was transmitted in cleartext. Any deployment using FTPSHook or FTPSFileTransmitOperator to move files over FTPS exposed file contents and credentials-in-transit to a network attacker able to observe the data connection. Upgrade apache-airflow-providers-ftp to 3.15.1 or later, which issues PROT P to encrypt the data channel.
