CVE-2025-58438Network attack vector

File overwrite via unvalidated download path

Published Sep 6, 2025 · Updated Nov 3, 2025

Path traversal in Internet Archive internetarchive before 5.5.1 allows attackers to write files outside the download directory. The File.download() method joins an archive-supplied filename to the destination and writes to the resolved path without sanitizing the name or confirming that the path remains beneath that destination. Triggering the flaw requires a user or application to download an attacker-controlled archive item; the resulting overwrite is limited to files writable by that process.
