SCA: security update for jupyter-server (GHSA-24qx-w28j-9m6p)

high Tenable Self-Hosted Container Security Plugin ID 441546

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Jupyter Server is the backend for Jupyter web applications. In versions 2.17.0 and earlier, the Origin
 header validation uses Python's re.match() to check incoming origins against the allow_origin_pat
 configuration value. Because re.match() only anchors at the start of the string and does not require a
 full match, a pattern intended to match only a trusted domain (e.g., trusted.example.com) will also match
 any origin that begins with that domain followed by additional characters (e.g.,
 trusted.example.com.evil.com). An attacker who controls such a domain can bypass the CORS origin
 restriction and make cross-origin requests to the Jupyter Server API from an untrusted site. This issue
 has been fixed in version 2.18.0. (CVE-2026-40110)

Solution

Update the jupyter-server library and its related packages to version 2.18.0 or later.
