{"id":"CVE-2020-26215","details":"Jupyter Notebook before version 6.1.5 has an Open redirect vulnerability. A maliciously crafted link to a notebook server could redirect the browser to a different website. All 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. The issue is patched in version 6.1.5.","aliases":["BIT-jupyter-base-notebook-2020-26215","BIT-jupyter-notebook-2020-26215","GHSA-c7vm-f5p4-8fqh","PYSEC-2020-215"],"modified":"2026-04-09T07:03:43.651851Z","published":"2020-11-18T22:15:11.947Z","related":["GHSA-c7vm-f5p4-8fqh","MGASA-2020-0457","MGASA-2022-0323","openSUSE-SU-2021:0024-1","openSUSE-SU-2021:0078-1","openSUSE-SU-2021:0117-1"],"references":[{"type":"ADVISORY","url":"https://github.com/jupyter/notebook/security/advisories/GHSA-c7vm-f5p4-8fqh"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00004.html"},{"type":"FIX","url":"https://github.com/jupyter/notebook/commit/3cec4bbe21756de9f0c4bccf18cf61d840314d74"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jupyter/notebook","events":[{"introduced":"0"},{"fixed":"e946154112daa5ef997d7f549953cce91b336d3d"},{"fixed":"3cec4bbe21756de9f0c4bccf18cf61d840314d74"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"6.1.5"}]}}],"versions":["4.0.0","4.0.1","4.1.0","5.0.0","5.0.0-rc.1","5.0.0b1","5.0.0b2","5.0.0rc2","5.1.0","5.1.0rc1","5.1.0rc3","5.2.0","5.2.0rc1","5.3.0","5.3.0rc1","5.3.1","5.4.0","5.5.0","5.5.0rc1","5.6.0","5.6.0rc1","5.7.0","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://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-26215.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
