CVE-2026-40961Apache Airflow: Open Redirect Bypass Vulnerability

Updated under an hour ago ()

Does this affect you?

It affects Apache Software Foundation Apache Airflow and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
