CVE-2026-22870 · GuardDog Zip Bomb Vulnerability in safe_extract() Allows DoS

This page contains facts from public vulnerability sources. Check the original advisory before updating.

GuardDog is a CLI tool to identify malicious PyPI packages. Prior to 2.7.1, GuardDog's safe_extract() function does not validate decompressed file sizes when extracting ZIP archives (wheels, eggs), allowing attackers to cause denial of service through zip bombs. A malicious package can consume gigabytes of disk space from a few megabytes of compressed data. This vulnerability is fixed in 2.7.1.
