NVD Description

Note: Versions mentioned in the description apply only to the upstream jupyterhub package and not the jupyterhub package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

JupyterHub 1.1.0 allows CSRF in the admin panel via a request that lacks an _xsrf field, as demonstrated by a /hub/api/user request (to add or remove a user account).
