Echo: apache-airflow-providers-ftp: security update to 3.15.1

high Tenable Self-Hosted Container Security Plugin ID 465244

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-49486)

Solution

Update the apache-airflow-providers-ftp library and its related packages to version 3.15.1 or later.
