Published Jun 8, 2026 · Updated Jun 8, 2026

Reflected XSS in itsourcecode.com Hospital Management System in PHP 1.0 allows remote attackers to run script via patientid.

Exploitation requires no authentication but does require a victim to open a crafted URL; the script then runs in that victim's browser session.
