CVE-2026-58116

Full vulnerability record from the local CVENow database.

Description

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.

La aplicación pasa la entrada de la ruta del modelo proporcionada por el usuario sin validar a AutoTokenizer.from_pretrained() y AutoModel.from_pretrained() con un parámetro trust_remote_code=True codificado de forma rígida, lo que hace que la biblioteca Hugging Face transformers obtenga y ejecute código arbitrario desde un repositorio de modelos remoto o local con los privilegios del proceso del servidor."
