CVE-2022-43985Network attack vector

Untrusted-site redirection via unsafe origin validation

Published Nov 2, 2022 · Updated May 2, 2025

Open redirect in Apache Airflow before 2.4.2 allows remote attackers to redirect users through the webserver's /confirm endpoint. The get_safe_url helper returned a supplied origin without first resolving it against the request host, allowing browser-normalized values to escape the intended host. Exploitation requires a user to follow an attacker-crafted link; it can send the browser to an untrusted site but does not interrupt Airflow.
