A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2 :authority field, discarding the original request-target authority. This inconsistency can allow an attacker to bypass security controls in Netty-based proxies or gateways, potentially leading to unauthorized access, cache poisoning, or misrouting of requests.","score":8.2,"severity":"high","published":"2026-09-18T14:27:54.015Z","modified":"2026-11-06T17:12:30.642Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red
