CVE-2026-94134

Apache Airflow SSH provider, Apache Airflow SFTP provider: SSH hook disables host-key verification by default

Published Oct 15, 2026 · updated Oct 16, 2026 · Apache Software Foundation Apache Airflow SSH provider

The Apache Airflow SSH provider hook disables SSH host-key verification by default: unless is configured or is explicitly set to false, it accepts any server key. This affects SSH and SFTP connections that rely on the default. An attacker in a machine-in-the-middle position between the worker and the SSH or SFTP server can impersonate the server and capture the credentials or data a task sends. Users of apache-airflow-providers-ssh and apache-airflow-providers-sftp are recommended to upgrade to apache-airflow-providers-ssh 7.0.0 and apache-airflow-providers-sftp 7.0.0 or later. The deferrable SFTP code paths had the same default and are covered separately by CVE-2026-94135; apache-airflow-providers-sftp 7.0.0 fixes both.
