Browser script execution via unencoded query parameters

Published Dec 1, 2025 · Updated Dec 1, 2025

Reflected XSS in Blood Bank Management System 1.0 login.php allows attackers to run JavaScript through crafted msg or error parameters. The included message.php template echoes either GET value directly into the HTML response without contextual output encoding. A victim must open the crafted login URL; the payload then executes in that page's browser context, allowing access to page-readable data and actions available there.
