Reflected XSS via unsanitized page parameter
Published Mar 8, 2026 · Updated Mar 8, 2026
Reflected XSS in SourceCodester Loan Management System 1.0 allows remote attackers to execute JavaScript through a crafted page parameter. Within /index.php, the GET page value used for dynamic routing is inserted into the HTML response without sanitization, so a closing-script payload creates and runs a new script element. Exploitation requires a victim to open the crafted URL; the resulting code runs in the application's browser origin and can alter displayed content or act with the victim's session.
