AI-suggested
Upgrade apache-airflow-providers-ftp to version 3.15.1 or later, which issues the PROT P command to encrypt the FTPS data channel. This official fix ensures that both control and data channels are protected by TLS. No other mitigations are indicated by the vendor advisory.
Description
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.
