The secondary vLLM hosts open a `SUB` ZeroMQ socket and connect to an `XPUB` socket on the primary vLLM host. When data is received on this `SUB` socket, it is deserialized with `pickle`. The issue lies with this deserialization, which can be exploited to execute <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2023-38620-integer-overflow-vulnerabilities-in-gtkwave-3-3-115-leading-to-arbitrary-code-execution\/\"  data-wpil-monitor-id=\"43235\">arbitrary code<\/a> on a remote machine.<br \/>\nAn attacker, having compromised the primary vLLM host, could abuse this <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-31644-command-injection-vulnerability-in-icontrol-rest-and-big-ip-tmos-shell\/\"  data-wpil-monitor-id=\"45545\">vulnerability to compromise the rest<\/a> of the hosts in the vLLM deployment.
