Summary

`uncbv`: archive extraction is vulnerable to path traversal (zip-slip)

Details

Summary

uncbv extract writes each archive entry to output_dir.join(entry_filename) using the filename stored in the archive with no check for .. components or absolute paths. A malicious .cbv / .cbz archive whose entry name contains ../ (or an absolute path) can therefore cause files to be written outside the output directory chosen by the user. This is a "zip-slip" / directory-traversal arbitrary file write (CWE-22).
