NVD description
vLLM before 0.28.0 contains a remote code execution vulnerability in the LlavaOnevision2 processor loader that ignores the trust_remote_code parameter when loading remote processor classes. Attackers can craft a malicious model with arbitrary code in processing_llava_onevision2.py that executes with vLLM process authority even when trust_remote_code is set to False.
What to do
- Upgrade vLLM to
0.28.0or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
