A Stored Cross-Site Scripting (XSS) vulnerability has been identified in CubeCart versions 6.0.0 through 6.5.9. This vulnerability allows an attacker with administrative privileges to inject malicious JavaScript payloads into various product fields. These payloads are then stored in the database and executed when users, including other administrators, view the affected product pages, potentially leading to session hijacking or unauthorized actions. The vulnerability is resolved in CubeCart version 6.6.0.
Impact en Aanvalsscenarioswordt vertaald…
Successful exploitation of CVE-2026-39428 allows an attacker to inject arbitrary JavaScript code into CubeCart product pages. This code executes in the context of the user viewing the page, enabling the attacker to steal session cookies, redirect users to malicious websites, or perform actions on behalf of the user, including modifying product information or accessing sensitive data. The impact is particularly severe for administrators, as an attacker could gain full control over the CubeCart installation. This vulnerability shares similarities with other XSS vulnerabilities where user input is not properly sanitized before being stored and displayed, potentially leading to account takeover and data breaches.
