Vulnerability Report: GO-2023-1568

• CVE-2022-41722
• Affects: path/filepath
• Published: Feb 16, 2023
• Modified: Jun 12, 2023

A path traversal vulnerability exists in filepath.Clean on Windows. On Windows, the filepath.Clean function could transform an invalid path such as "a/../c:/b" into the valid path "c:\b". This transformation of a relative (if invalid) path into an absolute path could enable a directory traversal attack. After fix, the filepath.Clean function transforms this path into the relative (but still invalid) path ".\c:\b".
