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:usersscope, they may escalate their own privileges by making themselves a full admin user. The impact is relatively small in thatadmin:usersis already an extremely privileged scope only granted to trusted users. In effect,admin:usersis equivalent toadmin=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.groupspermissions from granting themselves or other users permissions via group membership, which is intentional. Versions 4.1.6 and 5.1.0 fix this issue. - References
