Descriptions
In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could conduct PHP object injection attacks via crafted metadata in a wp.getMediaItem XMLRPC call. This is caused by mishandling of serialized data at phar:// URLs in the wp_get_attachment_thumb_file function in wp-includes/post.php.
En WordPress, en versiones anteriores a la 4.9.9 y versiones 5.x anteriores a la 5.0.1, los contribuyentes pueden llevar a cabo ataques de inyección de objetos PHP mediante metadatos manipulados en una llamada wp.getMediaItem. Esto viene provocado por la gestión incorrecta de datos serializados en URL phar:// en la función wp_get_attachment_thumb_file en wp-includes/post.php.
