NVD Description

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

JupyterHub through 6.0.1 contains an identifier collision vulnerability that allows authenticated users to overwrite another user's named-server OAuth client by registering a hyphenated username. Attackers holding a name like alice-prod can overwrite the client for alice's server prod, breaking OAuth login and revoking tokens by stopping their own server.
