CVE-2026-54844Network attack vector

Unauthenticated test manipulation via unsigned bot requests

Published Jun 25, 2026 · Updated Jun 25, 2026

Missing authorization in CheckView – Form & Checkout Testing 2.1.0 and earlier allows remote attackers to manipulate automated tests. The is_bot() path accepts bot-designated requests without verifying an RS256-signed header, activating authentication, CAPTCHA, and form-action bypasses reserved for tests. No account or user interaction is required, but the published impact is limited to integrity and no specific privileged endpoint or modified field is disclosed.
