{"id":"DEBIAN-CVE-2024-41942","details":"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.","modified":"2026-09-15T09:03:03.541633611Z","published":"2024-08-08T15:15:17.527Z","upstream":["CVE-2024-41942"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-41942"}],"affected":[{"package":{"name":"jupyterhub","ecosystem":"Debian:12","purl":"pkg:deb/debian/jupyterhub?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.0+ds1-1","5.0.0+ds1-1","5.0.0+ds1-2","5.0.0+ds1-3","5.0.0+ds1-4","5.2.1+ds1-1","5.2.1+ds1-2","5.2.1+ds1-3","5.2.1+ds1-4","5.2.1+ds1-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-41942.json"}},{"package":{"name":"jupyterhub","ecosystem":"Debian:13","purl":"pkg:deb/debian/jupyterhub?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.2.1+ds1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-41942.json"}},{"package":{"name":"jupyterhub","ecosystem":"Debian:14","purl":"pkg:deb/debian/jupyterhub?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.2.1+ds1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-41942.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
