vLLM is a language model serving platform that processes multimodal requests from clients. An attacker can send a specially crafted request to the unauthenticated /tokenize endpoint that causes vLLM to execute arbitrary Python code when the model uses dynamic processor code and trust_remote_code is enabled, potentially compromising the entire API process and any models or data it has access to.
