Upstream source description

Flower before 2.2.0 contains a cross-site request forgery vulnerability because Tornado xsrf_cookies is disabled and the OAuth session cookie lacks SameSite. Attackers can lure authenticated users to malicious pages that POST to /api/worker/shutdown, /api/worker/pool/restart, or /api/task/revoke to shut down Celery workers, resize pools, and revoke tasks.
