MEDIUM5.9EPSS 0.02%apache-airflow-providers-smtp: No certificate validation on SMTP STARTTLS connections in SMTP provider
發布日:2026/4/30修改日:2026/6/2
描述
Apache Airflow's SMTP provider `SmtpHook` called Python's `smtplib.SMTP.starttls()` without an SSL context, so no certificate validation was performed on the TLS upgrade. A man-in-the-middle between the Airflow worker and the SMTP server could present a self-signed certificate, complete the STARTTLS upgrade, and capture the SMTP credentials sent during the subsequent `login()` call. Users are advised to upgrade to the `apache-airflow-providers-smtp` version that contains the fix.
