CVE-2025-13456Public exploitNetwork attack vector

Script execution via unescaped orderby parameter

Published Jan 2, 2026 · Updated Jan 2, 2026

Reflected XSS in RadiusTheme ShopBuilder before 3.2.2 allows remote attackers to run script via a crafted category-archive URL. The category-archive ordering control writes the orderby query parameter into page output without sanitization or contextual escaping. A Shop and Category Archive template must be active, and a targeted administrator must open the URL and click the injected ordering element, allowing script to run with that user's site privileges.
