CVE-2026-93573 Io.netty/netty-codec-http: netty split transfer-encoding fields bypass final-chunked validation and enable request smuggling

A flaw was found in Netty's HTTP/1.1 decoder. This vulnerability allows a remote attacker to bypass Transfer-Encoding header validation by splitting the Transfer-Encoding field across multiple headers, with the last field containing a non-final transfer coding like gzip or deflate. This bypass ca...
