CVE-2026-58065Network attack vector

Git server impersonation via disabled host verification

Published Jul 13, 2026 · Updated Jul 13, 2026

Key-exchange authentication failure in Apache Airflow Git Provider before 0.4.1 allows man-in-the-middle attackers to impersonate Git servers. The Git hook defaults strict_host_key_checking to no and directs known_hosts to /dev/null, causing SSH transport to accept any presented server host key. Reachability requires a network-path position and a deployment that clones through the Git DAG bundle or provider over SSH with a deploy key; the attacker can steal that key or inject repository content.
