This discrepancy can be exploited in rare cases where a reverse proxy interprets the same input differently, potentially enabling HTTP request smuggling attacks such as bypassing access controls or corrupting responses.",

"text": "This issue is considered Moderate rather than Important because successful exploitation depends on a very specific deployment condition: the presence of an intermediary reverse proxy that both mishandles lone LF characters in chunk extensions and forwards them unmodified to Netty. 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.",
