Mooncake through 0.3.13.post1 contains a missing authentication vulnerability in the HTTP metadata server /metadata handler that allows unauthenticated attackers to read, overwrite, and delete transfer engine metadata keys. Attackers can poison segment descriptors such as tcp_data_port or re-create rpc_meta entries to redirect KV cache transfers to attacker-controlled listeners, or exhaust server memory.
