What is CVE-2025-53002?

A remote code execution vulnerability was identified in LLaMA-Factory, which is a tuning library for large language models. The flaw occurs during the training process when the application loads the vhead_file without implementing appropriate safeguards. This oversight allows attackers to exploit the vulnerability by passing a malicious Checkpoint path parameter through the WebUI, enabling arbitrary code execution on the host system without user awareness. The issue arises from the lack of the secure parameter weights_only=True during file loading. Users are advised to upgrade to version 0.9.4, which addresses and resolves this security issue.
