This is due to insufficient sanitization and validation of user-submitted field values before passing them to PHP's eval() function. The sanitize_values() method strips HTML tags but does not escape single quotes or prevent PHP code injection. This makes it possible for unauthenticated attackers to execute arbitrary code on the server by submitting a crafted value to a WCPA text field configured with custom pricing formula (pricingType: \"custom\" with {this.value})."},{"lang":"es","value":"El plugin Woocommerce Custom Product Addons Pro para WordPress es vulnerable a ejecución remota de código en todas las versiones hasta la 5.4.1, inclusive, a través de la fórmula de precios personalizada eval() en la función process_custom_formula() dentro de includes/process/price.php. Esto se debe a una sanitización y validación insuficientes de los valores de campo enviados por el usuario antes de pasarlos a la función eval() de PHP. El método sanitize_values() elimina las etiquetas HTML pero no escapa las comillas simples ni previene la inyección de código PHP.
