LLaMA-Factory Allows Arbitrary Code Execution via Unsafe Deserialization in Ilamafy_baichuan2.py

LLama Factory enables fine-tuning of large language models. Prior to version 1.0.0, a critical vulnerability exists in the `llamafy_baichuan2.py` script of the LLaMA-Factory project. The script performs insecure deserialization using `torch.load()` on user-supplied `.bin` files from an input directory. An attacker can exploit this behavior by crafting a malicious `.bin` file that executes arbitrary commands during deserialization. This issue has been patched in version 1.0.0.

LLaMA-Factory 安全漏洞

LLaMA-Factory是中国hoshi-hiyouga个人开发者的一个微调大型语言模型。 LLaMA-Factory 1.0.0之前版本存在安全漏洞，该漏洞源于llamafy_baichuan2.py脚本中对用户提供的.bin文件执行不安全的反序列化，可能导致执行任意代码。
