Vulnerability Title
peft Unsafe Deserialization via torch.load() Without weights_only in LoRA-GA and CorDA Modules
Source: CVE Program / CVE List V5
Vulnerability Description
Hugging Face peft's LoRA-GA and CorDA initialization modules (src/peft/tuners/lora/corda.py lines ~102 and ~163, and src/peft/tuners/lora/loraga.py line ~101) call torch.load() on config-specified cache/covariance files without weights_only=True, bypassing peft's own safe-loading wrapper used elsewhere in the codebase. Because torch.load() without weights_only=True performs full pickle deserialization, loading a malicious cache or covariance file (e.g. a shared/downloaded LoRA-GA or CorDA cache) results in arbitrary code execution.

Vulnerability Title
Hugging Face PEFT 反序列化注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Hugging Face PEFT是Hugging Face公司的一个参数高效微调模型库。 Hugging Face PEFT 0.19.1及之前版本存在反序列化注入漏洞，该漏洞源于src/peft/tuners/lora/corda.py和src/peft/tuners/lora/loraga.py中的LoRA-GA和CorDA初始化模块在加载配置指定的缓存/协方差文件时调用torch.load()且未设置weights_only=True，绕过安全加载包装器，导致反序列化恶意文件时可执行任意代码。
