This occurs because CSRF protection is mishandled, and because Search Engine Optimization of A elements is performed incorrectly, leading to XSS. The XSS results in administrative access, which allows arbitrary changes to .php files. This is related to wp-admin/includes/ajax-actions.php and wp-includes/comment.php."

Esto ocurre debido a que la protecci\u00f3n CSRF se gestiona de manera incorrecta y porque la optimizaci\u00f3n del motor de b\u00fasqueda de los elementos A se realiza incorrectamente, lo que desemboca en Cross-Site Scripting (XSS).
