CVE-2025-15223Public exploitNetwork attack vector

Script execution via insufficient Username filtering

Published Dec 31, 2025 · Updated Dec 31, 2025

Cross-site scripting in Simple-PHP-Blog login.php allows remote attackers to execute script through a crafted Username value. The login error path places the incompletely filtered Username value into an HTML attribute, so a quote can inject an event handler. No authentication is required, but a user must interact with the rendered element; successful exploitation runs script in that page's browser context.
