Hi,
The following vulnerability was published for jupyterhub.
CVE-2024-41942[0]:
| 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. In 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
