Hi,

The following vulnerability was published for netty.

CVE-2026-41417[0]:
| 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.
