Below is a conceptual example of an arbitrary payload that could potentially exploit this vulnerability.

import zmq
import pickle
# Set up a ZeroMQ context
context = zmq.Context()
# Set up a SUB socket and connect to the XPUB socket on the primary vLLM host
subscriber = context.socket(zmq.SUB)
subscriber.connect("tcp://localhost:5556")
# Listen for data on the SUB socket
while True:
[address, contents] = subscriber.recv_multipart()
# Deserialize the received data with pickle
payload = pickle.loads(contents)
# An arbitrary payload that executes code on the remote machine
exec(payload)
