{"schema_version": "1.6.1", "id": "CVE-2026-49486", "summary": "FTP Provider does not protect FTPS data channel (missing PROT_P)", "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"fixed": "3.15.1"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/67946"}, {"type": "WEB", "url": "https://lists.apache.org/thread/gwnsxlt9hfj5pc543wxtogbnjdn04xj1"}]}
