Vulnerability Title
Cornac < 2.6.0 Path Traversal via _extract_archive() in download.py
Vulnerability Description
Cornac before 2.6.0 contains a path traversal (Tar Slip) vulnerability that allows attackers to write arbitrary files outside the intended cache directory by supplying a crafted TAR archive containing ../ sequences, absolute paths, or symlink/hardlink entries to the _extract_archive() function in cornac/utils/download.py. Attackers can trigger this vulnerability through the built-in dataset loaders, which automatically download and extract archives, causing archive.extractall() to write files to arbitrary locations on the filesystem accessible to the running process.

Vulnerability Title
PreferredAI cornac 路径遍历漏洞
Vulnerability Description
PreferredAI cornac是PreferredAI公司的一款协同过滤推荐算法库。 PreferredAI cornac 2.6.0之前版本存在路径遍历漏洞,该漏洞源于包含../序列、绝对路径或符号链接/硬链接条目的特制TAR存档,当传递给cornac/utils/download.py中的_extract_archive()函数时,会导致路径遍历(Tar Slip)攻击,攻击者可通过内置数据集加载器自动下载并提取存档,从而将文件写入文件系统上运行进程可访问的任意位置。
