etcd: etcd: Authorization bypass allows information disclosure and denial of service

A flaw was found in etcd, a distributed key-value store. Unauthorized users can bypass authentication or authorization checks when the gRPC API is exposed to untrusted clients. This allows them to access sensitive cluster topology information, disrupt operations through alarms, interfere with lea...
