CVE-2025-53002

Summary

LLaMA-Factory is a tuning library for large language models. A remote code execution vulnerability was discovered in LLaMA-Factory versions up to and including 0.9.3 during the LLaMA-Factory training process. This vulnerability arises because the vhead_file is loaded without proper safeguards, allowing malicious attackers to execute arbitrary malicious code on the host system simply by passing a malicious Checkpoint path parameter through the WebUI interface. The attack is stealthy, as the victim remains unaware of the exploitation. The root cause is that the vhead_file argument is loaded without the secure parameter weights_only=True. Version 0.9.4 contains a fix for the issue.
