serde_with: KeyValueMap serialization panics on empty sequence or map entries

Summary The public KeyValueMap serializer assumes that each mapped element has at least one field or item to use as the map key, but it subtracts 1 from the caller-visible length before validating that assumption. An application that serializes attacker-controlled data through serdeasas =...
