{"id":"CVE-2024-41942","aliases":["BIT-jupyterhub-2024-41942","GHSA-9x4q-3gxw-849f","PYSEC-2024-200"],"url":"https://o3.security/vulnerability/CVE-2024-41942","summary":"JupyterHub has a privilege escalation vulnerability with the `admin:users` scope","details":"### Summary\n\nIf a user is granted the `admin:users` scope, they may escalate their own privileges by making themselves a full admin user.\n\n### Details\n\nThe `admin:users` scope allows a user to edit user records:\n\n> admin:users\n>\n> Read, write, create and delete users and their authentication state, not including their servers or tokens.\n>\n> -- https://jupyterhub.readthedocs.io/en/stable/rbac/scopes.html#available-scopes\n\nHowever, this includes making users admins. Admin users are granted scopes beyond `admin:users` making this a mechanism by which granted scopes may be escalated.\n\n### Impact\n\nThe 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.\n\nNote 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.","published":"2024-08-08T14:36:44.498Z","modified":"2026-08-12T03:51:37.317997862Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.0059,"percentile":0.45209,"asOf":"2026-08-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"jupyterhub","fixedVersion":"4.1.6"},{"ecosystem":"PyPI","name":"jupyterhub","fixedVersion":"5.1.0"}],"fix":{"url":"https://github.com/jupyterhub/jupyterhub/commit/99e2720b0fc626cbeeca3c6337f917fdacfaa428","label":"jupyterhub/jupyterhub@99e2720"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41942.json"},{"type":"ADVISORY","url":"https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-9x4q-3gxw-849f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41942"},{"type":"FIX","url":"https://github.com/jupyterhub/jupyterhub/commit/99e2720b0fc626cbeeca3c6337f917fdacfaa428"},{"type":"FIX","url":"https://github.com/jupyterhub/jupyterhub/commit/ff2db557a85b6980f90c3158634bf924063ab8ba"},{"type":"PACKAGE","url":"https://github.com/jupyterhub/jupyterhub"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/jupyterhub/PYSEC-2024-200.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:37.317997862Z"}}
