Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

LMdeploy versions 0.9.1 before 0.10.2 are vulnerable to remote code execution through the RPC server in zmq_rpc.py, which deserializes received messages with pickle.loads() without sanitization. An attacker who can reach the RPC port over the network can send a malicious pickle payload and run arbitrary commands on the host. Upgrade to LMdeploy 0.10.2, which binds the RPC server to localhost.
