Man-in-the-middle

Apache Airflow is vulnerable to Man-in-the-middle. The vulnerability is due to the lack of certificate validation when using the SMTP provider SmtpHook, where a man-in-the-middle between the Airflow worker and the SMTP server could present a self-signed certificate and capture the SMTP credential...

📄 Apache Airflow Databricks Provider Certificate Verification Bypass

The Apache Airflow Databricks Provider package disables TLS certificate verification when communicating with the Kubernetes API server during federated token exchange. Both the synchronous and asynchronous code paths use verify=False / ssl=False, allowing any attacker with network access within t...
