DescriptionGitHub Advisory

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.

AnalysisAI

LLama Factory enables fine-tuning of large language models. Rated medium severity (CVSS 6.1), this vulnerability is low attack complexity. Public exploit code available.
