Summary
The Slider Hero plugin for WordPress up to version 9.1.7 is vulnerable to second-order SQL Injection via the qcld_sliderhero_duplicate() function. Slide data is safely stored, but during slider duplication, values are concatenated without preparation, allowing administrators to inject additional SQL queries and extract sensitive data.
Risk Assessment
Risk of database data leakage, including admin data and configuration, potentially leading to full site compromise.
Recommendation
Update the Slider Hero plugin to the latest version. Restrict access to administrative functions and monitor admin activities.
Original NVD description (English source)
The Slider Hero plugin for WordPress is vulnerable to second-order SQL Injection in versions up to, and including, 9.1.7 via the qcld_sliderhero_duplicate() function. Slide data (description, title, btn, btn2, image_link, custom, etc.) is stored safely via $wpdb->update() with %s placeholders in the qchero_save_image AJAX handler, but when an administrator triggers the 'heroduplicateslider' task, qcld_sliderhero_duplicate() re-reads every slide column and concatenates the raw values directly into an INSERT VALUES tuple that is then executed with $wpdb->query() — with no $wpdb->prepare(), esc_sql(), or _real_escape_string in between. 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.
