CVSS 7.5 HIGH
A flaw was found in gRPC-Go. Servers created with xds.NewGRPCServer() can be exploited by a remote client sending a malformed RPC request that lacks the required :authority or Host headers. This can trigger an index-out-of-bounds panic, leading to the termination of the entire server process and a Denial of Service (DoS). In some deployments, this attack can be unauthenticated.
