Remote Code Execution

A security flaw exists in lmsys sglang versions ≥ 0.4.6 and ≤ 0.5.3. The vulnerability arises from the use of unsafe pickle deserialization of the serialized_named_tensors parameter in the /update_weights_from_tensor API endpoint, which could allow a remote attacker to execute arbitrary code on the server by sending a specially crafted payload.
