GHSA-2V4P-QF9Q-27WJ gRPC-Go xDS servers: Denial of Service (DoS) via crash due to missing `:authority` and `Host` headers

A vulnerability exists in gRPC-Go servers configured with xds.NewGRPCServer where a crafted request missing both :authority and Host headers can cause a server panic, resulting in a Denial of Service DoS. Servers built with xds.NewGRPCServer install an xDS routing interceptor on every RPC. This...

GHSA-QC2Q-P7WX-3PX3 gRPC-Go: xDS RBAC HTTP Filter bypass via mixed-case Header Matching and gRFC A41 validation evasion

Summary A vulnerability in the xDS RBAC HTTP filter implementation in grpc-go allows remote attackers to bypass authorization policies specifically DENY rules by using mixed-case or canonical-case header matchers e.g., X-Role instead of x-role. Additionally, the safety guards introduced by gRFC A...
