CVE-2026-49486 – Apache Airflow FTP provider: FTP Provider does not protect FTPS data channel (missing PROT_P)

CVE ID :CVE-2026-49486

Published : June 26, 2026, 7:05 a.m. | 39 minutes ago

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.

Severity: 0.0 | NA
