Details from the advisory
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.

Details from the advisory
The Slider Hero plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.2.0. This is due to missing or incorrect nonce validation on the qc_slider_hero_duplicate() function. This makes it possible for unauthenticated attackers to duplicate slides via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
