Summary
The Shopping Cart & eCommerce Store plugin for WordPress is vulnerable to generic SQL Injection via the 'product_order' parameter in all versions up to, and including, 5.9.2 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 administrator-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 is a second-order SQL injection: the payload is written to the ec_pageoption table via the ec_ajax_save_page_options handler — which applies no sanitization to raw $_POST values — and is later retrieved with stripslashes() (bypassing WordPress magic-quotes protection) before being concatenated directly into SQL on every store page render.
