| description: |- |
| 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". |
