A maliciously crafted link to a jupyter server could redirect the browser to a different website. All jupyter servers are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-601"],"references":["https://github.com/jupyter-server/jupyter_server/blob/master/CHANGELOG.md#106---2020-11-18","https://github.com/jupyter-server/jupyter_server/commit/3d83e49090289c431da253e2bdb8dc479cbcb157","https://github.com/jupyter/jupyter_server/security/advisories/GHSA-grfj-wjv9-4f9v","https://github.com/jupyter-server/jupyter_server/blob/master/CHANGELOG.md#106---2020-11-18","https://github.com/jupyter-server/jupyter_server/commit/3d83e49090289c431da253e2bdb8dc479cbcb157"],"products":["jupyter:jupyter_server"],"source":"nvd","synced_at":"2026-10-19T21:11:20.317016139+00:00"},"epss":{"cve":"CVE-2020-26232","score":0.01004,"percentile":0.62965,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-grfj-wjv9-4f9v","url":"https://osv.dev/vulnerability/GHSA-grfj-wjv9-4f9v","summary":"Open redirect in Jupyter Server","modified":"2026-09-10T03:48:35.837724184Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server","purl":"pkg:pypi/jupyter-server","ranges":["<1.0.6"],"fixed":["1.0.6"]}]},{"id":"PYSEC-2020-234","url":"https://osv.dev/vulnerability/PYSEC-2020-234","summary":"","modified":"2023-11-08T04:03:15.400330Z","packages":[{"ecosystem":"PyPI","name":"jupyter-server","purl":"pkg:pypi/jupyter-server","ranges":["<1.0.6"],"fixed":["1.0.6"]}]}],"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).
