Overview

vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs

Affected versions of this package are vulnerable to Arbitrary Code Injection via the config class named Nemotron_Nano_VL_Config. An attacker can execute arbitrary code on the host system by publishing a repository with a crafted configuration that references a malicious backend through the auto_map field, which is then fetched and executed even if remote code execution is explicitly disabled.
