aliases:
- CVE-2026-35592
- GHSA-mvwx-582f-56r7
details: pyLoad is a free and open-source download manager written in Python. Prior
  to 0.5.0b3.dev97, the _safe_extractall() function in src/pyload/plugins/extractors/UnTar.py
  uses os.path.commonprefix() for its path traversal check, which performs character-level
  string comparison rather than path-level comparison. This allows a specially crafted
  tar archive to write files outside the intended extraction directory. The correct
  function os.path.commonpath() was added to the codebase in the CVE-2026-32808 fix
  (commit 5f4f0fa) but was never applied to _safe_extractall(), making this an incomplete
  fix. This vulnerability is fixed in 0.5.0b3.dev97.
