Resteasy-netty4-cdi: resteasy-netty4: resteasy-reactor-netty: http request smuggling leading to client timeouts in resteasy-netty4

Vulnerability Description

A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk.
