CVE-2022-40754Network attack vector

Open redirect via unvalidated origin parameter

Published Sep 21, 2022 · Updated May 27, 2025

Open redirect in Apache Airflow 2.3.0 through 2.3.4 allows remote attackers to redirect users through the webserver's /confirm endpoint. The confirm view passes the user-controlled origin query parameter to Flask's redirect operation without restricting its scheme or host. Exploitation requires a user to follow a crafted link, after which the trusted Airflow origin sends the browser to an attacker-chosen site.
