{"id":"BIT-jupyterhub-2024-41942","summary":"JupyterHub has a privilege escalation vulnerability with the `admin:users` scope","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.\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.","aliases":["CVE-2024-41942","GHSA-9x4q-3gxw-849f","PYSEC-2024-200"],"modified":"2026-09-08T08:48:23.759233610Z","published":"2024-08-10T07:22:10.997Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:jupyter:jupyterhub:*:*:*:*:*:python:*:*"]},"references":[{"type":"FIX","url":"https://github.com/jupyterhub/jupyterhub/commit/99e2720b0fc626cbeeca3c6337f917fdacfaa428"},{"type":"FIX","url":"https://github.com/jupyterhub/jupyterhub/commit/ff2db557a85b6980f90c3158634bf924063ab8ba"},{"type":"ADVISORY","url":"https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-9x4q-3gxw-849f"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41942"}],"affected":[{"package":{"name":"jupyterhub","ecosystem":"Bitnami","purl":"pkg:bitnami/jupyterhub"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.1.6"},{"introduced":"5.0.0"},{"fixed":"5.1.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/jupyterhub/BIT-jupyterhub-2024-41942.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
