MobSF Path Traversal in GET /download/<filename> using absolute filenames

SummaryThe GET /download/ route uses string path verification via os.path.commonprefix, which allows an authenticated user to download files outside the DWDDIR download directory from "neighboring" directories whose absolute paths begin with the same prefix as DWDDIR e.g., .../downloadsbak,...

GHSA-MVWX-582F-56R7 pyload-ng: Incomplete Tar Path Traversal Fix in UnTar._safe_extractall via os.path.commonprefix Bypass

Summary The safeextractall 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...

Path Traversal

dbt-common is vulnerable to Path traversal. The vulnerability is due to the use of os.path.commonprefix for validating extraction paths, where commonprefix compares paths character‑by‑character rather than by path components, and an attacker can exploit this by providing a malicious tarball that...
