{"id":"GHSA-c7vm-f5p4-8fqh","summary":"Open redirect in Jupyter Notebook","details":"### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nOpen redirect vulnerability - a maliciously crafted link to a notebook server could redirect the browser to a different website.\n\nAll notebook servers are technically affected, however, these maliciously crafted links can only be reasonably made for known notebook server hosts. A link to your notebook server may *appear* safe, but ultimately redirect to a spoofed server on the public internet.\n\n### Patches\n\n_Has the problem been patched? What versions should users upgrade to?_\n\nPatched in notebook 6.1.5\n\n\n### References\n\n[OWASP page on open redirects](https://cheatsheetseries.owasp.org/cheatsheets/Unvalidated_Redirects_and_Forwards_Cheat_Sheet.html)\n\n### For more information\n\nIf you have any questions or comments about this advisory, or vulnerabilities to report, please email our security list [security@ipython.org](mailto:security@ipython.org).\n\nCredit: zhuonan li of Alibaba Application Security Team","aliases":["BIT-jupyter-base-notebook-2020-26215","BIT-jupyter-notebook-2020-26215","CVE-2020-26215","PYSEC-2020-215"],"modified":"2026-03-13T22:15:03.897641Z","published":"2020-11-18T21:06:36Z","related":["CVE-2020-26215"],"database_specific":{"cwe_ids":["CWE-601"],"github_reviewed_at":"2020-11-18T21:05:41Z","github_reviewed":true,"nvd_published_at":null,"severity":"LOW"},"references":[{"type":"WEB","url":"https://github.com/jupyter/notebook/security/advisories/GHSA-c7vm-f5p4-8fqh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-26215"},{"type":"WEB","url":"https://github.com/jupyter/notebook/commit/3cec4bbe21756de9f0c4bccf18cf61d840314d74"},{"type":"PACKAGE","url":"https://github.com/jupyter/notebook"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/notebook/PYSEC-2020-215.yaml"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00004.html"}],"affected":[{"package":{"name":"notebook","ecosystem":"PyPI","purl":"pkg:pypi/notebook"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.5"}]}],"versions":["0.0.0","4.0.0","4.0.1","4.0.2","4.0.4","4.0.5","4.0.6","4.1.0","4.2.0","4.2.0b1","4.2.1","4.2.2","4.2.3","4.3.0","4.3.1","4.3.2","4.4.0","4.4.1","5.0.0","5.0.0b1","5.0.0b2","5.0.0rc1","5.0.0rc2","5.1.0","5.1.0rc1","5.1.0rc2","5.1.0rc3","5.2.0","5.2.0rc1","5.2.1","5.2.1rc1","5.2.2","5.3.0","5.3.0rc1","5.3.1","5.4.0","5.4.1","5.5.0","5.5.0rc1","5.6.0","5.6.0rc1","5.7.0","5.7.1","5.7.10","5.7.11","5.7.12","5.7.13","5.7.14","5.7.14a0","5.7.15","5.7.16","5.7.2","5.7.3","5.7.4","5.7.5","5.7.6","5.7.8","5.7.9","6.0.0","6.0.0rc1","6.0.1","6.0.2","6.0.3","6.1.0","6.1.0rc1","6.1.1","6.1.2","6.1.3","6.1.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/11/GHSA-c7vm-f5p4-8fqh/GHSA-c7vm-f5p4-8fqh.json","last_known_affected_version_range":"\u003c= 6.1.4"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:N/SI:L/SA:L"}]}
