CubeCart is an ecommerce software solution. Prior to 6.7.0, an unauthenticated Reflected XSS vulnerability exists in the CubeCart v6.x search feature. Due to a logic flaw in classes/catalogue.class.php, user input is reflected without sanitization only when a search returns exactly one product. This flaw bypasses current filters, allowing an attacker to execute malicious JavaScript in the victim's browser, leading to session hijacking, site defacement, or phishing. This vulnerability is fixed in 6.7.0.
