LLMs could control their host machines by exploiting inference engines

Large language models could potentially gain control of their host machines by exploiting vulnerabilities in inference engines like vLLM or SGLang, which process and execute the tokens the models generate. The complexity of parsing diverse token sequences and chat formats across hundreds of model architectures creates opportunities for bugs that could allow malicious LLMs to emit token sequences that are misinterpreted as executable code rather than data, as demonstrated by a real vulnerability (CVE-2025-9141) that allowed arbitrary code execution through improper handling of tool-call parameters.
