CVE-2026-3714 Details
Description
A vulnerability has been found in OpenCart 4.0.2.3. Affected by this issue is the function Save of the file admin/controller/design/template.php of the component Incomplete Fix CVE-2024-36694. Such manipulation leads to improper neutralization of special elements used in a template engine. The attack may be performed from remote. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side template injection vulnerability has been identified in OpenCart version 4.0.2.3. This issue arises in the template editor functionality, specifically within the 'Save' function of the file 'admin/controller/design/template.php'. The vulnerability is a regression of CVE-2024-36694, which previously identified a similar issue in the theme editor of the same OpenCart version. Although the codebase was refactored to address the vulnerability, the core issue remains unremediated. The 'Save' method still accepts user-supplied Twig template code via POST input and stores it directly in the database without any sanitization or validation. As a result, when the modified template is rendered on the frontend, the injected code executes server-side. An authenticated administrator can exploit this vulnerability to achieve remote code execution as the web server user, potentially including reverse shell access.
