Vulnerability Title
Path Traversal Vulnerability in keras-team/keras via Tar Archive Extraction in keras.utils.get_file()
Vulnerability Description
Keras version 3.11.3 is affected by a path traversal vulnerability in the keras.utils.get_file() function when extracting tar archives. The vulnerability arises because the function uses Python's tarfile.extractall() method without the security-critical filter='data' parameter. Although Keras attempts to filter unsafe paths using filter_safe_paths(), this filtering occurs before extraction, and a PATH_MAX symlink resolution bug triggers during extraction. This bug causes symlink resolution to fail due to path length limits, resulting in a security bypass that allows files to be written outside the intended extraction directory. This can lead to arbitrary file writes outside the cache directory, enabling potential system compromise or malicious code execution. The vulnerability affects Keras installations that process tar archives with get_file() and does not affect versions where this extraction method is secured with the appropriate filter parameter.

Vulnerability Title
Keras 路径遍历漏洞
Vulnerability Description
Keras是Keras开源的一个多后端深度学习框架。 Keras 3.11.3版本存在路径遍历漏洞，该漏洞源于keras.utils.get_file函数在提取tar归档时存在路径遍历问题，可能导致任意文件写入。
