CVSS 3.1
9.0 criticalCVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVE-2025-29783
Critical (9.0) in vllm vllm. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in vllm 0.8.0.
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.
