Hi,

The following vulnerability was published for netty.

CVE-2025-67735[0]:
| 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.
