CVE-2026-49486

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.

Summary		(es) El ’FTPSHook.get_conn()’ del proveedor FTP de Apache Airflow creó una conexión ’ftplib.FTP_TLS’ pero nunca llamó a ’prot_p()’, por lo que, aunque el canal de control estaba protegido por TLS, el canal de datos se transmitía en texto claro. Cualquier implementación que utilice ’FTPSHook’ o ’FTPSFileTransmitOperator’ para mover archivos a través de FTPS expuso el contenido de los archivos y las credenciales en tránsito a un atacante de red capaz de observar la conexión de datos. Actualice apache-airflow-providers-ftp a la versión ’3.15.1’ o posterior, que emite ’PROT P’ para cifrar el canal de datos.
