NVD Description
Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
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.
