Doc Text:
A flaw was found in vllm-project/vllm. A hardcoded setting in the model implementation files bypasses the user's explicit security configuration, which is intended to prevent the execution of remote code. This allows a remote attacker to achieve remote code execution by providing a malicious model from a HuggingFace repository. The vulnerability primarily impacts deployments loading NemotronVL or KimiK25 models, potentially leading to system compromise.

Description OSIDB Bzimport 2026-05-28 19:01:43 UTC 
vllm-project/vllm version 0.14.1 contains a vulnerability where the `trust_remote_code=True` parameter is hardcoded in two model implementation files (`vllm/model_executor/models/nemotron_vl.py` and `vllm/model_executor/models/kimi_k25.py`). This bypasses the user's explicit `--trust-remote-code=False` setting, enabling remote code execution via malicious HuggingFace model repositories. This issue is an incomplete fix for CVE-2025-66448 and CVE-2026-22807, as it affects separate code paths in model implementation files. Deployments loading NemotronVL or KimiK25 models are particularly impacted.
