CVE-2025-66572Public exploitNetwork attack vector

Browser code execution via search template evaluation

Published Dec 4, 2025 · Updated May 26, 2026

Client-side template injection in Loaded Commerce 6.6 allows remote attackers to execute code in a visitor's browser via a crafted search URL. The search-results template evaluates the keywords parameter as template syntax instead of rendering it as inert text, causing arithmetic input to return its computed value. No authentication is needed to create the URL, but a victim must visit it; successful exploitation runs script with the storefront's browser privileges.
