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."

Los atacantes pueden engañar a usuarios autenticados a páginas maliciosas que realicen un POST a /api/worker/shutdown, /api/worker/pool/restart o /api/task/revoke para detener los workers de Celery, redimensionar los pools y revocar tareas."
