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.
