CVE-2023-51312Public exploitNetwork attack vector

Browser script execution via unencoded date parameter

Published Feb 20, 2025 · Updated Nov 4, 2025

Reflected XSS in PHPJabbers Restaurant Booking System 3.0 allows remote authenticated users to run script in another user's browser. The Reservations Schedule view places the date parameter into generated HTML without neutralizing executable markup, so a crafted value is interpreted as browser code. Exploitation requires low-privilege access and a victim to open the crafted request; the resulting script can read or alter data available to that browser session.
