CVE-2026-16229Public exploitNetwork attack vector

Unauthenticated reflected XSS via unencoded page parameter

Published Jul 19, 2026 · Updated Jul 19, 2026

Reflected cross-site scripting in index.php in itsourcecode.com Courier Management System 1.0 allows remote attackers to run script via page. The page parameter is inserted directly into the response without output encoding, so a crafted URL executes JavaScript in the victim's browser context. Exploitation requires no authentication but does require a victim to visit the crafted URL, enabling actions within that browser session.
