> 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.
