The Apache Airflow Git provider runs its git-over-SSH operations with
StrictHostKeyChecking=noby default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server (man-in-the-middle), capturing the SSH deploy key or injecting malicious repository content. Deployments that use the Git DAG bundle or Git provider to clone over SSH with a deploy key are affected. The fix changes the default to verify host keys; upgrade to apache-airflow-providers-git0.4.1or later and configure aknown_hostsfile.References
