Unauthenticated script execution via password-reset email input

Published Sep 23, 2026 · Updated Sep 23, 2026

Cross-site scripting in onSite internet GmbH Auktion:NG 20260722 allows remote attackers to execute script through its password-reset endpoint. The /forgotpasswd.html handler processes the email argument without sufficient output neutralization, allowing crafted markup to enter the generated page. The endpoint is public and requires no authenticated account; successful injection executes attacker-controlled script in a browser that renders the crafted response.
