Vulnerability from github – Published: 2026-06-26 09:30 – Updated: 2026-06-26 21:32

Details

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

7.5 (High)

CVE-2026-49486 (GCVE-0-2026-49486)

Vulnerability from cvelistv5 – Published: 2026-06-26 07:05 – Updated: 2026-06-26 18:36

Title

Apache Airflow FTP provider: FTP Provider does not protect FTPS data channel (missing PROT_P)

Summary

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.
