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.","published":"2020-11-24T21:15:11.557Z","modified":"2026-07-09T00:06:23.485421Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"jupyter-server","fixedVersion":"1.0.6"}],"fix":{"url":"https://github.com/jupyter-server/jupyter_server/commit/3d83e49090289c431da253e2bdb8dc479cbcb157","label":"jupyter-server/jupyter_server@3d83e49"},"references":[{"type":"ADVISORY","url":"https://github.com/jupyter-server/jupyter_server/blob/master/CHANGELOG.md#106---2020-11-18"},{"type":"ADVISORY","url":"https://github.com/jupyter/jupyter_server/security/advisories/GHSA-grfj-wjv9-4f9v"},{"type":"FIX","url":"https://github.com/jupyter-server/jupyter_server/commit/3d83e49090289c431da253e2bdb8dc479cbcb157"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T00:06:23.485421Z"}}
