By itself, Netty\u2019s parsing quirk does not introduce risk, and in most real-world environments, reverse proxies normalize or reject malformed chunked requests, preventing smuggling. As a result, the vulnerability has limited reach, requires a niche configuration to be exploitable, and does not universally expose Netty-based servers to request smuggling\u2014hence it is rated moderate in severity rather than important or critical.",
