CVE-2022-29923Network attack vector

Administrator-gated script execution via unescaped parameters

Published Jul 20, 2022 · Updated Apr 28, 2026

Reflected XSS in ThingsForRestaurants Quick Restaurant Reservations 1.4.1 and earlier allows remote authenticated users to execute scripts. Several request parameters reach generated pages without sufficient input sanitization or output escaping, reflecting attacker-supplied script content into the response. Administrator access is required to initiate the request, and execution requires a user to open the crafted response; the script then runs in the victim's browser context.
