CVE-2025-66455

LMDeploy is a toolkit for compressing, deploying, and serving large language models. Starting in version 0.9.2 and prior to version 0.16.0, LMDeploy's PyTorch DistServe/PD-disaggregation control plane used recvpyobj to deserialize messages received through a ZeroMQ PULL socket. PyZMQ implements...

LMDeploy has Remote Code Execution by Pickle Deserialization via handle_zmq_recv in lmdeploy/lmdeploy/pytorch/disagg/conn/engine_conn.py

Summary LMDeploy's PyTorch DistServe/PD-disaggregation control plane used recvpyobj to deserialize messages received through a ZeroMQ PULL socket. PyZMQ implements recvpyobj using Python pickle deserialization, which can execute arbitrary code while reconstructing an object. The peer address used...

CVE-2025-66455

LMDeploy versions 0.9.2 through 0.15.x are vulnerable to unauthenticated remote code execution (CVSS 9.8 Critical ) in its PyTorch DistServe/PD-disaggregation control plane. The root cause is that recv_pyobj() in EngineP2PConnection.handle_zmq_recv() performs pickle deserialization on messages re...
