CVE-2026-54646

CubeCart is an ecommerce software solution that prior to version 6.7.3 allowed admins with document edit permissions to save raw PHP code in the Invoice Editor. When any admin clicks Print, the rendered template is saved in a file that can be executed by unauthenticated users.

CubeCart prior to version 6.7.2 has a vulnerability that allows an attacker to take over a user account by manipulating links in emails. An attacker can exploit the Host header to send a malicious link to the victim, leading to account takeover.

In CubeCart prior to version 6.6.0, authenticated time-based blind SQL injection vulnerabilities were identified in the sorting parameters (sort[price], sort_activity, sort_admin, and sort_customer) of the Products and Logs endpoints. This allows an attacker to execute arbitrary SQL commands, compromising the confidentiality and integrity of the database.

CubeCart prior to version 6.7.0 has an Authenticated Server-Side Template Injection (SSTI) vulnerability in multiple modules, including Email Templates, Invoices, Documents, and Contact Forms. The application unsafely evaluates user-supplied input, allowing authenticated users with administrative privileges to execute arbitrary operating system commands.

CubeCart prior to version 6.7.0 contained an Authenticated Arbitrary File Upload vulnerability in the REST API File Manager endpoint. This allows any holder of an API key with files:rw permission to upload PHP files to the images/source/ directory, where they are executed by the web server.

CubeCart prior to version 6.7.0 has an Authenticated Server-Side Template Injection (SSTI) vulnerability in multiple modules, including Email Templates and Documents. The application unsafely evaluates user-supplied input through the Smarty template engine.

In CubeCart prior to 6.7.5, the GDPR tools rely on page-level CC_PERM_READ access and do not require CC_PERM_DELETE for purge, no_order_purge, or delete_guests commands. An authenticated administrator with read-only customer privileges can invoke these backend actions directly to bypass interface restrictions and irreversibly delete customer records, accounts without orders, or guest accounts.

CubeCart is an ecommerce software solution. Prior to 6.7.5, admin/sources/settings.index.inc.php directly concatenates the administrator-controlled download_expire POST parameter into a raw UPDATE statement for CubeCart_downloads without numeric validation. An authenticated administrator can supply a comma-delimited value that changes the SET clause because HTML sanitization does not neutralize SQL syntax, allowing manipulation of database columns and potentially other data within the application's database privileges. This issue is fixed in version 6.7.5.

In CubeCart prior to 6.7.5, admin/sources/products.index.inc.php reads rich-text fields from $GLOBALS['RAW']['POST'] and removes only script elements before storing and rendering through Smarty templates. An administrator with product-editing rights can store event-handler attributes, SVG content, or javascript: URIs that bypass this filter, causing persistent JavaScript execution when a storefront visitor or another administrator views the product content.

In CubeCart prior to 6.7.5, the _errorMessage method uses strip_tags to permit anchor elements in error, information, and warning messages while retaining unsafe href values and onclick event handlers. Attacker-controlled search or input data that reaches a GUI message can carry a javascript: URI or event handler through the filter, and viewing or interacting with the rendered anchor executes JavaScript in the victim's browser session.
