MEDIUM CVE-2026-15351 Deferred

WC Vendors REST status parameter permits Shop Manager SQL injection

WC Vendors through 2.7.0 accepts a Shop Manager-controlled status value through its REST API and uses it in SQL without adequate preparation. sanitize_text_field() removes HTML but not SQL metacharacters, and the REST server unslashes GET parameters before sanitization. A Shop Manager can therefore append SQL and extract sensitive database information. The public.

Source record

Technical description

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.
