      "value": "JupyterHub is software that allows one to create a multi-user server for Jupyter notebooks. Prior to versions 4.1.6 and 5.1.0, if a user is granted the `admin:users` scope, they may escalate their own privileges by making themselves a full admin user. The impact is relatively small in that `admin:users` is already an extremely privileged scope only granted to trusted users.\nIn effect, `admin:users` is equivalent to `admin=True`, which is not intended. Note that the change here only prevents escalation to the built-in JupyterHub admin role that has unrestricted permissions. It does not prevent users with e.g. `groups` permissions from granting themselves or other users permissions via group membership, which is intentional. Versions 4.1.6 and 5.1.0 fix this issue."

En efecto, `admin:users` es equivalente a `admin=True`, lo cual no es lo previsto. Tenga en cuenta que el cambio aqu\u00ed solo evita la escalada al rol de administrador integrado de JupyterHub que tiene permisos sin restricciones. No impide que los usuarios con, por ejemplo, permisos de \"grupos\" se otorguen permisos a s\u00ed mismos o a otros usuarios a trav\u00e9s de la membres\u00eda en un grupo, lo cual es intencional.
