Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
SQL Injection in the AI Copilot - Content Generator WordPress plugin (versions up to and including 1.5.4) exposes WordPress database contents to authenticated attackers with as little as subscriber-level access. The vulnerability resides in the unsanitized order[0][dir] parameter passed to an AJAX handler that lacks both input escaping and prepared statements, allowing appended SQL queries to extract sensitive information. No public exploit code or CISA KEV listing is identified at time of analysis, but the nonce exposure mechanism - which emits the required waic-nonce in front-end HTML whenever a [waic_form] or [aiwu-form] shortcode is rendered - lowers the practical exploitation bar for contributor-level users who can publish shortcodes.
Technical ContextAI
The flaw is a classic CWE-89 (SQL Injection) rooted in the absence of WordPress's $wpdb->prepare() on a dynamic query that accepts a user-controlled sort direction parameter (order[0][dir]). Vulnerable code paths are traceable to classes/model.php:L162, classes/table.php:L259, modules/workspace/controller.php:L17, and modules/workspace/models/tasks.php:L266. The AJAX handler enforces only nonce verification (waic-nonce) and performs no WordPress capability check, meaning any authenticated user who possesses a valid nonce can invoke it. The nonce itself is embedded in page HTML whenever the plugin's [waic_form] or [aiwu-form] shortcodes are rendered, making it obtainable by any user who can view - or in the contributor case, publish - such a page.
RemediationAI
A fix is recorded in the WordPress plugin SVN changeset at revision 3612849 (https://plugins.trac.wordpress.org/changeset?reponame=&old=3612849%40ai-copilot-content-generator&new=3612849%40ai-copilot-content-generator); however, a specific patched release version is not independently confirmed from the available input data - site administrators should update to the latest available version in the WordPress plugin directory and verify the installed version is newer than 1.5.4. As a compensating control prior to patching, administrators should disable open user registration to prevent untrusted subscriber accounts, and consider restricting access to WordPress AJAX endpoints (/wp-admin/admin-ajax.php) from untrusted network segments where operationally feasible. If shortcode-publishing permissions can be audited, restricting the [waic_form] and [aiwu-form] shortcodes to trusted roles reduces nonce exposure. The Wordfence WAF rule set may provide virtual patching for sites using Wordfence.
