WCVendors vulnerabilities and threats

Administrator SQL Injection in WC Vendors Marketplace <= 2.7.2.1 versions.

The WC Vendors – WooCommerce Multivendor, WooCommerce Marketplace, Product Vendors plugin for WordPress is vulnerable to generic SQL Injection via the 'status' parameter in all versions up to, and including, 2.7.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with shop manager-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 sanitize_text_field callback strips HTML but leaves SQL metacharacters intact, and wp_magic_quotes slash protection does not apply because WP_REST_Server::serve_request() calls wp_unslash() on GET parameters before the sanitize callback executes.

The WC Vendors – WooCommerce Multivendor, WooCommerce Marketplace, Product Vendors plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.6.4. This is due to missing or incorrect nonce validation on the /vendor_dashboard/product/delete/ endpoint. This makes it possible for unauthenticated attackers to delete vendor products via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
