How to fix?

Upgrade jupyter-server to version 1.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Open Redirect. A maliciously crafted link to a jupyter server could redirect the browser to a different website. All jupyter servers running without a base_url prefix 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. This same vulnerability was patched in upstream notebook v5.7.8.
