[https://nvd.nist.gov/vuln/detail/CVE-2025-67735]
h3. Description
Netty is an asynchronous, event-driven network application framework. In
versions prior to 4.1.129.Final and 4.2.8.Final, the
`io.netty.handler.codec.http.HttpRequestEncoder` has a CRLF injection with the
request URI when constructing a request. This leads to request smuggling when
`HttpRequestEncoder` is used without proper sanitization of the URI. Any
application / framework using `HttpRequestEncoder` can be subject to be abused
to perform request smuggling using CRLF injection. Versions 4.1.129.Final and
4.2.8.Final fix the issue.
Netty is constantly getting update, this seems like a legit reason as any.
