CVE-2025-46567: Hiyouga Llama-Factory

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Hiyouga Llama-Factory: before 1.0.0 (fixed in 1.0.0)
