CVE-2026-45361: Apache Airflow Google provider: SSH host key verification disabled in ComputeEngineSSHHook (paramiko AutoAddPolicy default)

Apache Airflow providers-google's `ComputeEngineSSHHook` disables SSH host-key verification by default, exposing SSH traffic between an Airflow worker and a Compute Engine VM to in-path network attackers who can intercept or modify the session. Users are advised to upgrade to `apache-airflow-providers-google` 22.0.0 or later.

Security readout for executives and security teams

This flaw can make Airflow SSH connections to Google Compute Engine VMs trust an attacker’s SSH host key by default. If an attacker can sit in the network path, they could intercept or alter the session. Apache advises upgrading the Google provider to 22.0.0 or later. Exposure is likely limited to Airflow deployments using apache-airflow-providers-google and ComputeEngineSSHHook to SSH into Compute Engine VMs. The bundle does not provide a precise affected version range beyond advising upgrade to 22.0.0 or later. Treat as high priority for Airflow environments that automate production VM access. The business risk is unauthorized visibility or modification of operational SSH sessions, but the attack requires network-path positioning. Patch confirmed exposure promptly. Mitigation focus: Upgrade apache-airflow-providers-google to 22.0.0 or later.; Review Apache advisory and patch PR for vendor-confirmed details.; Ensure ComputeEngineSSHHook connections verify SSH host keys..
