CVE-2019-20043

Estado: ModificadaMedia (4.3)—

En wp-includes / rest-api / endpoints / class-wp-rest-posts-controller.php en WordPress 3.7 a 5.3.0, los usuarios autenticados que no tienen los derechos para publicar una publicación pueden marcar publicaciones como fijas o antiadherente a través de la API REST. Por ejemplo, el rol de contribuyente no tiene tales derechos, pero esto les permitió evitarlo. Esto se ha solucionado en WordPress 5.3.1, junto con todas las versiones anteriores de WordPress desde 3.7 hasta la versión 5.3 a través de una versión menor.
