Key Points

  • vLLM is affected by CVE-2026-27893, where `--trust-remote-code=False` is silently ignored because Nemotron-VL and Kimi-K25 model files hardcode `trust_remote_code=True`.
  • This misconfiguration enables a malicious Hugging Face repository to achieve code execution on the inference server without warnings or log entries.
  • The issue impacts vLLM versions 0.10.1 through 0.17.x, while vLLM 0.18.0 reportedly includes the fix.
  • The advisory notes this is the third occurrence of the same vulnerability class in vLLM, but it manifests through different code paths each time.
Two vLLM model files hardcode `trust_remote_code=True`, overriding an explicit `False` setting with no warning or log entry. A malicious Hugging Face repository targeting either architecture can achieve code execution on the inference server. This is the third time the same vulnerability class has surfaced in vLLM, but in a different code path each time. Versions 0.10.1 through 0.17.x are affected; 0.18.0 contains the fix.
