Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') pada copier-org copier. Skor CVSS 3.1 4.4 (Medium) menurut github.com.

Deskripsi (NVD)

Copier is a library and CLI app for rendering project templates. Prior to version 9.14.1, Copier's _subdirectory setting is documented as the subdirectory to use as the template root. However, the current implementation accepts parent-directory traversal such as .. and uses it directly when selecting the template root. As a result, a template can escape its own directory and make Copier render files from the parent directory without --UNSAFE. This issue has been patched in version 9.14.1.
