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...
