Name of the Vulnerable Software and Affected Versions vLLM versions 0.5.2 through 0.8.5 Description The issue affects vLLM, a high-throughput and memory-efficient inference and serving engine for LLMs. In a multi-node vLLM deployment, vLLM uses ZeroMQ for some multi-node communication purposes,...

Denial Of Service (DoS)

vllm is vulnerable to Denial of Service DoS. The vulnerability is due to unbounded in-memory cache growth due to allowing unique schema requests to continually populate the grammar cache, potentially exhausting system RAM...

GHSA-GGPF-24JW-3FCW CVE-2025-24357 Malicious model remote code execution fix bypass with PyTorch < 2.6.0

Description https://github.com/vllm-project/vllm/security/advisories/GHSA-rh4j-5rhw-hr54 reported a vulnerability where loading a malicious model could result in code execution on the vllm host. The fix applied to specify weightsonly=True to calls to torch.load did not solve the problem prior to...

vLLM vulnerable to Denial of Service by abusing xgrammar cache

Impact This report is to highlight a vulnerability in XGrammar, a library used by the structured output feature in vLLM. The XGrammar advisory is here: https://github.com/mlc-ai/xgrammar/security/advisories/GHSA-389x-67px-mjg3 The xgrammar library is the default backend used by vLLM to support...

GHSA-PGR7-MHP5-FGJP vLLM deserialization vulnerability in vllm.distributed.GroupCoordinator.recv_object

vllm-project vllm version 0.6.0 contains a vulnerability in the distributed training API. The function vllm.distributed.GroupCoordinator.recvobject deserializes received object bytes using pickle.loads without sanitization, leading to a remote code execution vulnerability. Maintainer perspective...

GHSA-CJ47-QJ6G-X7R4 vLLM allows Remote Code Execution by Pickle Deserialization via AsyncEngineRPCServer() RPC server entrypoints

vllm-project vllm version 0.6.0 contains a vulnerability in the AsyncEngineRPCServer RPC server entrypoints. The core functionality runserverloop calls the function makehandlercoro, which directly uses cloudpickle.loads on received messages without any sanitization. This can result in remote code...
