CVE-2026-95596Network attack vectorHinoki check available

Browser script execution via search-term attribute breakout

Published Oct 9, 2026 · Updated Oct 9, 2026

Reflected XSS in RadiusTheme ShopBuilder 3.4.1 and earlier allows remote attackers to execute browser scripts via crafted search terms. The Product Archive widget embeds the search term in the data-rtsb-ajax attribute without preventing attribute breakout, allowing injected event handlers. Exploitation requires an affected archive rendering the crafted term and victim interaction; execution occurs in the site's browser context rather than on the server.
