Vulnerability Title
Diffusers Path Traversal via weight_map Arbitrary File Read
Source: CVE Program / CVE List V5
Vulnerability Description
Diffusers through 0.39.0, fixed in commit cee298c, contains a path traversal vulnerability in the _get_checkpoint_shard_files function that allows attackers to read arbitrary files by supplying malicious weight_map values in model index JSON. Attackers can use ../ sequences or absolute paths in weight_map entries to escape the model directory and read safetensors files outside the intended location during model loading.

Vulnerability Title
Hugging Face diffusers 路径遍历漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Hugging Face diffusers是Hugging Face公司开源的一个生成图像、音频和3D分子结构的扩散模型库。 Diffusers 0.39.0及之前版本存在路径遍历漏洞，该漏洞源于_get_checkpoint_shard_files函数中存在路径遍历问题，允许攻击者通过提供恶意的weight_map值在模型索引JSON中读取任意文件。攻击者可利用../序列或绝对路径在weight_map条目中逃出模型目录，在模型加载期间读取指定位置外的safetensors文件。
