SCA: security update for io.netty:netty-codec-http (GHSA-6cqp-g7gg-8hr5)

medium Tenable Self-Hosted Container Security Plugin ID 445160

Description

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

- Netty is a network application framework for development of protocol servers and clients. Versions
4.2.0.Final through 4.2.15.Final and 4.1.0.Final through 4.1.135.Final, are vulnerable to security control
bypass during the origin evaluation process. CorsHandler provides a shortCircuit() configuration designed
to reject unauthorized cross-origin requests immediately, acting as a security control before requests
reach the application. However, due to a logical operator error in the origin evaluation process, this
protection can be entirely bypassed. An attacker can bypass the short-circuit mechanism by sending a
request with an Origin: null header. This failure forwards unauthorized requests to the backend
application, bypassing intended access controls. This issue is fixed in versions 4.1.136.Final and
4.2.16.Final. (CVE-2026-56746)

Solution

Update the io.netty:netty-codec-http library and its related packages to version 4.1.136.Final or later.
