Description
A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the is_safe_url check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to apache-airflow 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can place Airflow behind a reverse proxy that strips off-domain next= query parameters before they reach the login endpoint.
