Apache Airflow: login redirect route can be crafted to send users to an attacker-controlled origin

CVSS 7.2CVE-2026-40961Control plane, storage & DevOpscurated

Impact

The login redirect route accepted next= values that slipped past the is_safe_url check, so a link that starts on the trusted Airflow hostname lands the user on an origin the attacker controls. For an operator this is a phishing primitive against the people who hold Airflow credentials - the pipeline operators and platform engineers whose accounts can schedule work on the fleet - not a direct compromise of the scheduler or of any node. Impact is confined to the web tier; nothing here gives code execution or data access by itself.

Who can reach it

Anyone who can get an authenticated Airflow user to click a crafted URL on the Airflow domain. The description notes the bypass is reachable by authenticated users; the CVSS vector records PR:N.

What to do

Upgrade apache-airflow to 3.2.2 or later and restart the webserver. As defense in depth, the advisory suggests a reverse proxy in front of Airflow that strips off-domain next= query parameters before they reach the login endpoint - deployable without an Airflow restart.
