CVE-2026-44376 is an unauthenticated reflected cross-site scripting vulnerability in CubeCart v6.x prior to version 6.7.0. The issue affects the search feature and is caused by a logic flaw in classes/catalogue.class.php. User-supplied input is reflected back to the client without proper sanitization, but only in the specific case where a search query returns exactly one product. Because this code path bypasses existing filtering, an attacker can craft a malicious search request that causes arbitrary JavaScript to execute in a victim's browser when the victim follows the attacker-controlled link or otherwise triggers the request.
