vLLM Tool Schema allows DoS via Malformed pattern and type Fields

SummaryThe vLLM backend used with the /v1/chat/completions OpenAPI endpoint fails to validate unexpected or malformed input in the "pattern" and "type" fields when the tools functionality is invoked. These inputs are not validated before being compiled or parsed, causing a crash of the inference...

vLLM: temperature=NaN and temperature=Infinity bypass validation and propagate to GPU kernels

Summary All temperature validation gates use comparison operators , which silently evaluate to False for NaN and for positive Infinity in Python's IEEE 754 float semantics. Both values pass every guard and propagate to GPU sampling kernels, where they produce undefined behavior or CUDA errors tha...

CVE-2025-48944

vLLM (inference/serving engine) is affected when running versions 0.8.0 up to but excluding 0.9.0 with the /v1/chat/completions OpenAPI endpoint. The root cause is lack of validation for unexpected or malformed inputs in the pattern and type fields when the tools functionality is invoked, allowin...

vLLM 输入验证错误漏洞

vLLM is a high throughput and memory efficient inference and service engine for LLM from the vLLM open source. An input validation error vulnerability exists in vLLM versions prior to 0.8.0 through 0.9.0, which stems from accidental or malformed inputs in the pattern and type fields that are not...
