CVE-2026-44972: Datadog Guarddog

Medium severity, CVSS 5.0. EPSS: 0.2% chance of exploitation in the next 30 days.

GuardDog is a CLI tool to identify malicious PyPI packages. From 2.6.0 to 2.9.0, GuardDog includes attacker-controlled filenames, file locations, messages, and code snippets in its default human-readable output without escaping terminal control characters. A malicious package can therefore inject ANSI or OSC escape sequences into analyst terminals or CI logs.

Affected products

• Datadog Guarddog: from 2.6.0, up to and including 2.9.0
