AI Copilot <= 1.5.4 - Authenticated (Subscriber+) SQL Injection via 'order[0][dir]' Parameter

The AI Copilot – Content Generator plugin for WordPress is vulnerable to generic SQL Injection via 'order[0][dir]' Parameter in all versions up to, and including, 1.5.4 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. The required waic-nonce is emitted on the front-end whenever the [waic_form] or [aiwu-form] shortcode is rendered, enabling contributor-level users who can publish shortcodes to obtain a valid nonce and reach the vulnerable AJAX handler, which performs no capability check beyond nonce verification when the shortcodes are not already embedded in a page.
