CVE-2026-94135

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

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

The Apache Airflow SFTP provider's deferrable code paths ( , , ) disable SSH host-key verification by default unless the connection explicitly sets to false. Deployments that run SFTP sensors or operators in deferrable mode are affected. An attacker in a machine-in-the-middle position between the triggerer and the SFTP server can impersonate the server and capture the credentials or data exchanged. Users of apache-airflow-providers-sftp are recommended to upgrade to apache-airflow-providers-sftp 7.0.0 or later. This is a separate defect from CVE-2026-94134 (the synchronous SSH hook default, which also affects the SFTP hook); users who applied the fix for one also need this release for the other - apache-airflow-providers-sftp 7.0.0 fixes both.
