CVE-2026-8441
WP Review Slider Pro <= 12.7.2 - Unauthenticated SQL Injection via 'notinstring' Parameter
Description
The WP Review Slider Pro plugin for WordPress is vulnerable to SQL Injection via the 'notinstring' parameter of the wprp_load_more_revs AJAX action in versions up to, and including, 12.7.2. The parameter is read via $_POST['notinstring'] and passed through sanitize_text_field() — which strips HTML and whitespace but does not provide SQL safety. The value is then concatenated directly into a numeric/unquoted `AND id NOT IN (...)` clause and executed via $wpdb->get_results() without $wpdb->prepare() or intval() casting. Because the value sits in an unquoted numeric context, WordPress's wp_magic_quotes protection (which only escapes embedded quotes) is ineffective. The AJAX hook is registered via wp_ajax_nopriv_wprp_load_more_revs, and the required check_ajax_referer nonce is publicly available via wp_localize_script on any frontend page that renders the plugin shortcode, so an unauthenticated attacker who can reach a public page hosting the plugin can extract arbitrary data from the database via blind/time-based injection.

Action Type Old Value New Value Added Translation Title: plugin WP Review Slider Pro de https://wpreviewslider.com/ para WordPress, Description: El plugin WP Review Slider Pro para WordPress es vulnerable a inyección SQL a través del parámetro ’notinstring’ de la acción AJAX wprp_load_more_revs en versiones hasta la 12.7.2, inclusive. El parámetro se lee a través de parámetro y se pasa por sanitize_text_field() - que elimina HTML y espacios en blanco pero no proporciona seguridad SQL. El valor se concatena directamente en una cláusula numérica/sin comillas ’AND id NOT IN (...)’ y se ejecuta a través de $wpdb -> get_results() sin $wpdb -> prepare() ni la conversión intval(). Debido a que el valor se encuentra en un contexto numérico sin comillas, la protección wp_magic_quotes de WordPress (que solo escapa comillas incrustadas) es ineficaz. El hook AJAX se registra a través de wp_ajax_nopriv_wprp_load_more_revs, y el nonce check_ajax_referer requerido está disponible públicamente a través de wp_localize_script en cualquier página de frontend que renderice el shortcode del plugin, por lo que un atacante no autenticado que pueda acceder a una página pública que aloje el plugin puede extraer datos arbitrarios de la base de datos a través de inyección ciega/basada en tiempo. -
