SCA: security update for io.netty:netty-codec-http (GHSA-57rv-r2g8-2cj3)

critical Tenable Self-Hosted Container Security Plugin ID 441342

Description

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

 - Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and
 4.1.133.Final, HttpClientCodec pairs each inbound response with an outbound request by queue.poll() once
 per response, including for 1xx. If the client pipelines GET then HEAD and the server sends 103, then 200
 with GET body, then 200 for HEAD, the queue pairs HEAD with the first 200. The HEAD rule then skips
 reading that message’s body, so the GET entity bytes stay on the stream and the following 200 is parsed
 from the wrong offset. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final. (CVE-2026-42584)

Solution

Update the io.netty:netty-codec-http library and its related packages to version 4.1.133.Final or later.
