SCA: security update for io.undertow:undertow-core (GHSA-vqqj-9cmv-hx43)

critical Tenable Cloud Security Plugin ID 478368

Description

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

 - A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts
 with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This
 behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request
 smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted
 information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.
 (CVE-2026-28369)

Solution

Update the io.undertow:undertow-core library and its related packages to version 2.2.40.Final or later.
