Official description

The MultiVendorX – WooCommerce Multivendor Marketplace AI Powered Solutions plugin for WordPress is vulnerable to generic SQL Injection via the 'order_by' parameter in all versions up to, and including, 5.0.9 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 subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability is exploitable by any authenticated subscriber-level user when the plugin's store approval setting is configured to automatically approve store owners (described as the default), as this allows any logged-in user to self-register as a store_owner via the public Stores REST endpoint, thereby obtaining the edit_stores capability required to reach the vulnerable transactions endpoint.
