This is due to the Calculation Addon's process_filter() function concatenating user-submitted form field values into a PHP code string without proper escaping before passing it to eval(). The sanitize_text_field() function applied to input does not escape single quotes or other PHP code context characters. This makes it possible for unauthenticated attackers to inject and execute arbitrary PHP code on the server by submitting a crafted value in any string-type form field (text, email, URL, select, radio) when a form uses the \"Complex Calculation\" feature."}, {"lang": "es", "value": "El plugin Everest Forms Pro para WordPress es vulnerable a ejecuci\u00f3n remota de c\u00f3digo a trav\u00e9s de inyecci\u00f3n de c\u00f3digo PHP en todas las versiones hasta la 1.9.12, inclusive.
