FKIE_CVE-2020-26215

Vulnerability from fkie_nvd - Published: 2020-11-18 22:15 - Updated: 2026-06-17 03:07
Severity
4.4 (Medium) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:L
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
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.
