GHSA-7p3p-8qv8-m2vh
Summary Eclipse Jetty: HTTP Authority/Host mismatch Jetty currently accepts HTTP/2 and HTTP/3 requests where the regular Host header and the pseudo-header :authority do not match. As a result, the same request can carry two different host identities through Jetty: - logic based on `HttpURI` / `Request.getServerName(request)` uses `:authority` - logic based on raw request headers continues to use `Host` This creates a host/authority confusion condition that can break security assumptions in higher layers. Jetty already performs an explicit authority/Host consistency check on the HTTP/1.1 path, but equivalent validation is missing on the HTTP/2 and HTTP/3 paths.
