CVE-2026-22870

HIGH

datadoghq/guarddog < 2.7.1 - Denial of Service via ZIP Bomb Extraction

Title source: llm
STIX 2.1

Description

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.
