SCA: security update for io.netty:netty-codec-http (GHSA-v8h7-rr48-vmmv)

medium Tenable Cloud Security Plugin ID 441253

Description

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

 - Netty allows request-line validation to be bypassed when a `DefaultHttpRequest` or
 `DefaultFullHttpRequest` is created first and its URI is later changed via `setUri()`. The constructors
 reject CRLF and whitespace characters that would break the start-line, but `setUri()` does not apply the
 same validation. `HttpRequestEncoder` and `RtspEncoder` then write the URI into the request line verbatim.
 If attacker-controlled input reaches `setUri()`, this enables CRLF injection and insertion of additional
 HTTP or RTSP requests, leading to HTTP request smuggling or desynchronization on the HTTP side and request
 injection on the RTSP side. This issue is fixed in versions 4.2.13.Final and 4.1.133.Final.
 (CVE-2026-41417)

Solution

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