SGLang contains an arbitrary code execution vulnerability caused by the ZMQ message decoder unconditionally deserializing PickleWrapper payloads via pickle.loads() in _maybe_unwrap_pickle without type allowlisting or authentication; this vulnerability persists via the msgpack path even when SGLANG_USE_PICKLE_IPC is disabled, and becomes remotely exploitable if data-parallel attention is enabled with a non-loopback --dist-init-addr setting.
