Short explanation

The Apache Airflow SSH provider hook disables SSH host-key verification by default. S0, S1

Why does it matter?

A machine-in-the-middle attacker can impersonate the server and capture credentials or task data. S0, S1

What should be done?

  • Upgrade to apache-airflow-providers-ssh 7.0.0 S0
  • Upgrade to apache-airflow-providers-sftp 7.0.0 S0
  • Configure host_key or set no_host_key_check explicitly S0

Show the technical text from the sources

The Apache Airflow SSH provider hook disables SSH host-key verification by default: unless `host_key` is configured or `no_host_key_check` 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.
