CVE-2026-58116— LLaMA-Factory 0.9.5 Remote Code Execution via WebUI Model Path

Quick assessment

Affected
hiyouga LlamaFactory
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

hiyouga LLaMA-Factory是hiyouga个人开发者开源的一个大语言模型微调框架。 hiyouga LLaMA-Factory 0.9.5及之前版本存在安全漏洞，该漏洞源于应用将用户提供的未经验证的模型路径输入传递给AutoTokenizer.from_pretrained()和AutoModel.from_pretrained()函数，且硬编码trust_remote_code=True参数，可能导致具有WebUI访问权限的攻击者通过提供恶意的模型路径执行任意Python代码。

Vulnerability Title
LLaMA-Factory 0.9.5 Remote Code Execution via WebUI Model Path
Source: CVE Program / CVE List V5
Vulnerability Description
LLaMA-Factory through 0.9.5 contains a remote code execution vulnerability that allows attackers with WebUI access to execute arbitrary Python code by supplying a malicious model path in the Chat or Training interfaces. The application passes user-supplied model path input unvalidated into AutoTokenizer.from_pretrained() and AutoModel.from_pretrained() with a hardcoded trust_remote_code=True parameter, causing the Hugging Face transformers library to fetch and execute arbitrary code from a remote or local model repository with the privileges of the server process.
