{"cve":"CVE-2024-28179","nvd":{"published":"2024-03-20T20:15:08.680","modified":"2026-06-17T07:21:09.053","status":"Analyzed","description":"Jupyter Server Proxy allows users to run arbitrary external processes alongside their Jupyter notebook servers and provides authenticated web access. Prior to versions 3.2.3 and 4.1.1, Jupyter Server Proxy did not check user authentication appropriately when proxying websockets, allowing unauthenticated access to anyone who had network access to the Jupyter server endpoint. This vulnerability can allow unauthenticated remote access to any websocket endpoint set up to be accessible via Jupyter Server Proxy. In many cases, this leads to remote unauthenticated arbitrary code execution, due to how affected instances use websockets. The websocket endpoints exposed by `jupyter_server` itself is not affected. Projects that do not rely on websockets are also not affected. Versions 3.2.3 and 4.1.1 contain a fix for this issue.","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:H/A:H","score":9.8},"cwes":["CWE-306"],"references":["https://github.com/jupyterhub/jupyter-server-proxy/blob/9b624c4d9507176334b46a85d94a4aa3bcd29bed/jupyter_server_proxy/handlers.py#L433","https://github.com/jupyterhub/jupyter-server-proxy/commit/764e499f61a87641916a7a427d4c4b1ac3f321a9","https://github.com/jupyterhub/jupyter-server-proxy/commit/bead903b7c0354b6efd8b4cde94b89afab653e03","https://github.com/jupyterhub/jupyter-server-proxy/security/advisories/GHSA-w3vc-fx9p-wp4v","https://github.com/jupyterhub/jupyter-server-proxy/blob/9b624c4d9507176334b46a85d94a4aa3bcd29bed/jupyter_server_proxy/handlers.py#L433"],"products":["jupyter:jupyter_server_proxy"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-28179","score":0.0103,"percentile":0.63721,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w3vc-fx9p-wp4v","url":"https://osv.dev/vulnerability/GHSA-w3vc-fx9p-wp4v","summary":"Jupyter Server Proxy's Websocket Proxying does not require authentication","modified":"2026-06-10T17:14:18.340886644Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server-proxy","purl":"pkg:pypi/jupyter-server-proxy","ranges":[">=4.0.0 <4.1.1"],"fixed":["4.1.1"]},{"ecosystem":"PyPI","name":"jupyter-server-proxy","purl":"pkg:pypi/jupyter-server-proxy","ranges":["<3.2.3"],"fixed":["3.2.3"]}]},{"id":"PYSEC-2024-234","url":"https://osv.dev/vulnerability/PYSEC-2024-234","summary":"","modified":"2026-06-10T17:14:19.030800237Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server-proxy","purl":"pkg:pypi/jupyter-server-proxy","ranges":["<3.2.3",">=4.0.0 <4.1.1"],"fixed":["3.2.3","4.1.1"]}]}],"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).
