Jupyter Server on Windows has a vulnerability that lets unauthenticated attackers leak the NTLMv2 password hash of the Windows user running the Jupyter server. An attacker can crack this password to gain access to the Windows machine hosting the Jupyter server, or access other network-accessible machines or 3rd party services using that credential. Or an attacker perform an NTLM relay attack without cracking the credential to gain access to other network-accessible machines. This vulnerability is fixed in 2.14.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/jupyter-server/jupyter_server/commit/79fbf801c5908f4d1d9bc90004b74cfaaeeed2df","https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-hrw6-wg82-cm62","https://github.com/jupyter-server/jupyter_server/commit/79fbf801c5908f4d1d9bc90004b74cfaaeeed2df","https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-hrw6-wg82-cm62"],"products":["jupyter:jupyter_server"],"source":"nvd","synced_at":"2026-10-19T21:51:20.603330631+00:00"},"epss":{"cve":"CVE-2024-35178","score":0.00804,"percentile":0.56733,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hrw6-wg82-cm62","url":"https://osv.dev/vulnerability/GHSA-hrw6-wg82-cm62","summary":"Jupyter server on Windows discloses Windows user password hash","modified":"2026-09-10T03:50:15.612508359Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server","purl":"pkg:pypi/jupyter-server","ranges":["<2.14.1"],"fixed":["2.14.1"]}]},{"id":"PYSEC-2024-165","url":"https://osv.dev/vulnerability/PYSEC-2024-165","summary":"","modified":"2026-06-10T17:14:15.953806720Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server","purl":"pkg:pypi/jupyter-server","ranges":["<2.14.1"],"fixed":["2.14.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
