Smart Manager < 8.98.0 - Authenticated (Subscriber+) SQL Injection to Privilege Escalation via 'access_privileges' Parameter

Description

The Smart Manager – Advanced WooCommerce Bulk Edit & Inventory Management plugin for WordPress is vulnerable to generic SQL Injection via the 'access_privileges' parameter in all versions up to, and including, 8.97.0 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 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 exploit is only possible on installations where an administrator has saved a role-based deny-list Access Privilege configuration that does not explicitly block the internal 'access-privilege' module, as this condition allows the authorization filter to implicitly permit Subscriber-level users to invoke the vulnerable handler.
