Cubecart V6 vulnerabilities

CVE-2026-54648 Medium · 6.5 CWE-862 Sep 17, 2026

CubeCart: Missing Authorization Check in customers.gdpr.inc.php Leads to Unauthorized Customer Data Deletion

CubeCart is an ecommerce software solution. Prior to 6.7.5, the GDPR tools in admin/sources/customers.gdpr.inc.php rely on page-level CC_PERM_READ access and do not require CC_PERM_DELETE for the 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, compromising data integrity and availability. This issue is fixed in version 6.7.5.

CVE-2026-54647 High · 7.2 CWE-89 Sep 17, 2026

CubeCart : SQL Injection via download_expire Parameter in settings.index.inc.php

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.

CVE-2026-54646 High · 7.2 CWE-89 Sep 17, 2026

CubeCart: SQL Identifier Injection via Backtick Bypass in maintenance.index.inc.php

CubeCart is an ecommerce software solution. Prior to 6.7.5, admin/sources/maintenance.index.inc.php places administrator-controlled tablename values into ALTER TABLE, CHECK TABLE, and ANALYZE TABLE statements without validating the identifiers or escaping embedded backticks. An authenticated administrator can terminate the quoted identifier with a closing backtick and introduce attacker-controlled structural SQL, potentially compromising database confidentiality, integrity, and availability within the application's database privileges. This issue is fixed in version 6.7.5.

CVE-2026-54645 Medium · 4.8 CWE-79 Sep 17, 2026

CubeCart: Stored XSS in Product Description Editor via Global Sanitizer Bypass

CubeCart is an ecommerce software solution. Prior to 6.7.5, admin/sources/products.index.inc.php reads the description, description_short, and spec_copy rich-text fields from $GLOBALS['RAW']['POST'] and removes only script elements before the values are stored and rendered 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 and enabling session exposure or unauthorized browser-context actions. This issue is fixed in version 6.7.5.

CVE-2026-54644 Medium · 6.1 CWE-79 Sep 17, 2026

CubeCart: XSS via Anchor Tag Attribute Injection in gui.class.php Message System

CubeCart is an ecommerce software solution. Prior to 6.7.5, the _errorMessage method in classes/gui.class.php 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, enabling session exposure or unauthorized application actions. This issue is fixed in version 6.7.5.

CVE-2026-54643 Medium · 5.4 CWE-862 Sep 17, 2026

CubeCart: Missing Authorization Check for Order Note Deletion in orders.index.inc.php

CubeCart is an ecommerce software solution. Prior to 6.7.5, the delete-note handler in admin/sources/orders.index.inc.php verifies only the presence of order_id and delete-note parameters before deleting records from CubeCart_order_notes, without requiring CC_PERM_DELETE for orders. An authenticated administrator lacking order modification privileges can directly invoke the handler with valid identifiers and delete order-history notes, removing operational records and audit-trail data. This issue is fixed in version 6.7.5.

CVE-2026-54642 Medium · 5.3 CWE-352 Sep 17, 2026

CubeCart: CSRF Protection Missing for Download Resets and Card Deletions in orders.index.inc.php

CubeCart is an ecommerce software solution. Prior to 6.7.5, the reset_id download-counter action and delete_card stored-payment-card action in admin/sources/orders.index.inc.php use state-changing GET requests and are omitted from the protection map in admin/skins/default/csrf.inc.php. A remote attacker can induce an authenticated administrator to issue one of these requests without a validated session token, causing unintended resets of electronic download usage counters or deletion of stored customer payment-card tokens. This issue is fixed in version 6.7.5.

CVE-2026-45714 Critical · 9.1 CWE-94 May 13, 2026

CubeCart Server-Side Template Injection Leading to OS Command Execution (CVE-2026-45714)

CubeCart is an ecommerce software solution. Prior to 6.7.0, an Authenticated Server-Side Template Injection (SSTI) vulnerability exists in multiple modules of CubeCart (including Email Templates, Invoices, Documents, and Contact Forms). The application unsafely evaluates user-supplied input using the Smarty template engine without enabling Smarty Security Policies. This allows any authenticated user with administrative privileges to execute arbitrary operating system commands (RCE) on the server. This vulnerability is fixed in 6.7.0.

CVE-2026-45708 High · 7.2 CWE-94 May 13, 2026

CubeCart: Authenticated RCE via Invoice Template → Order Print

CubeCart is an ecommerce software solution. Prior to 6.7.3, an admin with documents edit permission can save raw <?php … ?> into the Invoice Editor. The next time any admin clicks Print on any order, the rendered template is written to files/print.<md5>.php. files/.htaccess ships an explicit <Files print.*.php> allow from all </Files> carve-out, so the file is fetched and executed by any unauthenticated visitor. This vulnerability is fixed in 6.7.3.

CVE-2026-45055 High · 8.1 CWE-20 May 13, 2026

CubeCart: Pre-Authenticated Password Reset Link Poisoning via HTTP Host Header

CubeCart is an ecommerce software solution. Prior to 6.7.2, CubeCart 6.6.x – 6.7.1 builds CC_STORE_URL directly from the Host request header at bootstrap, with no allowlist. The constant is embedded verbatim into transactional email links, most critically the password-reset link in User::passwordRequest() (and the admin equivalent in Admin::passwordRequest()). An unauthenticated attacker who knows a target email can POST /index.php?_a=recover with Host: evil.com; CubeCart writes a fresh verify token (valid 3,600 s) and emails the victim a link http://evil.com/index.php?_a=recovery&validate=<TOKEN>. The token is valid against the legitimate store — capturing the victim's click on evil.com yields full account takeover, or store takeover when an admin email is targeted. This vulnerability is fixed in 6.7.2.

CVE-2026-45054 Medium · 4.9 CWE-89 May 13, 2026

CubeCart: Authenticated SQL Injection via `sort[]` Parameter in Admin Orders Transactions Listing

CubeCart is an ecommerce software solution. Prior to 6.7.0, the admin orders-transactions listing page (admin.php?_g=orders&node=transactions) builds a raw ORDER BY SQL fragment from the attacker-controlled $_GET['sort'] array without column or direction validation. Both the column key and the direction value flow into the query string as bare SQL tokens, and the framework's sqlSafe() (mysqli escape_string) escapes only quote characters — none of which are required for ORDER BY injection. An authenticated administrator with the minimum CC_PERM_READ permission on orders can execute arbitrary SQL against the store database, including time-based blind extraction of admin password hashes, customer PII, and integrated payment-gateway credentials. This vulnerability is fixed in 6.7.0.

CVE-2026-45053 Critical · 9.1 CWE-434 May 13, 2026

CubeCart REST API File Manager: authenticated arbitrary file upload (CVE-2026-45053)

CubeCart is an ecommerce software solution. Prior to 6.7.0, an Authenticated Arbitrary File Upload vulnerability exists in the REST API File Manager endpoint (POST /api/v1/files) of CubeCart. The endpoint allows any holder of an API key with files:rw permission to upload PHP source files into the web-accessible images/source/ directory, where they are executed by the web server. Combined with a path-traversal flaw in the same endpoint's filepath parameter, a single API request writes a webshell anywhere the webserver process can write — including the document root — yielding full Remote Code Execution. This vulnerability is fixed in 6.7.0.

CVE-2026-44377 Critical · 9.1 CWE-94 May 13, 2026

CubeCart: Server-Side Template Injection (SSTI) in Smarty Templates leading to RCE

CubeCart is an ecommerce software solution. Prior to 6.7.0, an Authenticated Server-Side Template Injection (SSTI) vulnerability exists in multiple modules of CubeCart (including Email Templates and Documents). The application unsafely evaluates user-supplied input directly through the Smarty template engine. By leveraging this, an authenticated attacker with administrative privileges can bypass current restrictions and call native PHP functions within the templates, such as readgzfile() to read sensitive configuration files, or error_log() to write a malicious PHP web shell, ultimately achieving Information Disclosure and full Remote Code Execution (RCE). This vulnerability is fixed in 6.7.0.

CVE-2026-44376 Medium · 6.1 Public exploit CWE-79 May 13, 2026

CubeCart: Reflected XSS in Store Search Bar

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.

CVE-2026-39428 Medium · 4.8 CWE-79 May 13, 2026

CubeCart: Stored Cross-Site Scripting (XSS)

CubeCart is an ecommerce software solution. Prior to 6.6.0, a Stored Cross-Site Scripting (XSS) vulnerability exists in CubeCart v6.x. An attacker with administrative privileges can inject malicious JavaScript payloads into multiple fields during the creation or modification of a product. These payloads are stored in the database and executed whenever a user (customer or another administrator) views the affected product pages, which could lead to session hijacking or unauthorized actions. This vulnerability is fixed in 6.6.0.

CVE-2026-39358 High · 7.2 CWE-89 May 13, 2026

CubeCart: Time-based Blind SQL Injection

CubeCart is an ecommerce software solution. Prior to 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 in CubeCart v6.x. This allows an attacker to execute arbitrary SQL commands, compromising the confidentiality and integrity of the database. This vulnerability is fixed in 6.6.0.
