CVE-2022-45402Network attack vector

External-site redirect via unvalidated login destination

Published Nov 15, 2022 · Updated Apr 30, 2025

Open redirect in Apache Airflow's webserver before 2.4.3 allows remote attackers to send users to external sites through the login flow. The login view passed its user-controlled next parameter to Flask-AppBuilder's redirect helper instead of Airflow's same-origin get_safe_url check. Exploitation requires a user to complete an affected login flow, after which the browser is redirected to an attacker-chosen site for phishing.
