CVE-2026-40961 (opens in a new tab)How to fix?
Upgrade apache-airflow-core to version 3.2.2rc1 or higher.
Overview
Affected versions of this package are vulnerable to Open Redirect in the login redirect route, where the is_safe_url check can be bypassed. A user who can reach the login redirect route can redirect a user from the trusted Airflow domain to an attacker-controlled origin by crafting a login URL whose next= parameter evades the is_safe_url validation and convincing the target to follow it. Exploitation requires the target user to follow the crafted link, and the impact is limited to redirection to an external origin, which supports phishing or credential capture.
Workaround
This vulnerability can be avoided by using a reverse proxy that strips off-domain next= query parameters before they reach the login endpoint.
