DescriptionCVE.org

LLaMA-Factory through 0.9.5 contains a remote code execution vulnerability that allows attackers with WebUI access to execute arbitrary Python code by supplying a malicious model path in the Chat or Training interfaces. The application passes user-supplied model path input unvalidated into AutoTokenizer.from_pretrained() and AutoModel.from_pretrained() with a hardcoded trust_remote_code=True parameter, causing the Hugging Face transformers library to fetch and execute arbitrary code from a remote or local model repository with the privileges of the server process.

AnalysisAI

Remote code execution in LLaMA-Factory through version 0.9.5 allows attackers who can reach the Gradio WebUI to run arbitrary Python by entering a malicious model path in the Chat or Training interfaces. Because the app forwards unvalidated user input into Hugging Face's AutoTokenizer.from_pretrained() and AutoModel.from_pretrained() with a hardcoded trust_remote_code=True, a referenced repository's custom modeling code executes with the server process's privileges. …
