CVE-2026-49486 is a high-severity flaw (CVSS 7.5) affecting apache-airflow-providers-ftp. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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-ft
