Threat database

The Welcart e-Commerce plugin for WordPress contains an SQL Injection vulnerability in the 'wp_usces_order_old' parameter affecting all versions up to and including 2.12.4. Authenticated users with editor-level access or higher can exploit this flaw to append additional SQL queries, potentially extracting sensitive database information. The vulnerability arises from insufficient escaping and lack of proper query preparation. The CVSS score is 4.9, indicating a medium severity risk.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Settlement Notification Parameters in all versions up to, and including, 2.12.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The IPN endpoint accepts the 'rel' and 'option' parameters with no authentication, nonce validation, or signature verification, meaning any unauthenticated attacker can directly submit malicious payloads that are stored and later rendered in the administrator's settlement error log view.

The Welcart e-Commerce WordPress plugin up to version 2.12.1 contains a PHP Object Injection vulnerability via deserialization of untrusted data in the Telecom EDY payment callback. Unauthenticated attackers can inject arbitrary order metadata during checkout and later trigger deserialization without validation, enabling file deletion on the server, including critical files like wp-config.php. Exploitation requires an admin to print an invoice to trigger the file deletion, potentially leading to remote code execution if the WordPress installer is rerun with attacker-controlled data.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_order' parameter in all versions up to, and including, 2.12.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload is delivered via the guest checkout form, requiring no authentication, and executes when an administrator views the affected order in the WordPress admin panel.

The Welcart e-Commerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'usces_export' action in all versions up to, and including, 2.11.24. This makes it possible for unauthenticated attackers to access configured payment credentials (ex. PayPal api secret) , as well as business contact details, mail templates, and other operational settings tied to the store.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'order_mail' setting in versions up to, and including, 2.11.22. This is due to insufficient sanitization on the order_mail field and a lack of escaping on output. This makes it possible for authenticated attackers, with Editor-level permissions and above, to inject arbitrary web scripts via the General Setting page that will execute when an administrator accesses the E-mail Setting page.

The Welcart e-Commerce plugin for WordPress is vulnerable to SQL Injection via the cookie in all versions up to, and including, 2.11.21 due to insufficient escaping on the user supplied value and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via settings in all versions up to, and including, 2.11.20 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 2.11.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
