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 /tokenize API endpoint, which does not enforce authentication even when the --api-key option is configured. An unauthenticated remote attacker can access the endpoint directly, bypassing the API key requirement entirely.

Note: This is only exploitable when --api-key is configured and no external proxy enforces authentication on the /tokenize route.
