CVE-2025-29783 Details
Description
vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. When vLLM is configured to use Mooncake, unsafe deserialization exposed directly over ZMQ/TCP on all network interfaces will allow attackers to execute remote code on distributed hosts. This is a remote code execution vulnerability impacting any deployments using Mooncake to distribute KV across distributed hosts. This vulnerability is fixed in 0.8.0.
A remote code execution vulnerability has been identified in vLLM, a high-throughput inference engine for large language models. This issue arises when vLLM is configured to use Mooncake, as it exposes unsafe deserialization over ZMQ/TCP on all network interfaces. Attackers can exploit this vulnerability to execute remote code on distributed hosts. The problem is rooted in the Mooncake Pipe, which, by design, allows public access to certain sockets over the network, facilitating the exploitation of deserialization vulnerabilities. This vulnerability affects vLLM versions 0.6.5 through 0.8.0.
This vulnerability has been fixed in vLLM version 0.8.0.
