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.

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.
Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform various Cross-Side Scripting (XSS) and PHP injections attacks, delete files, leak potentially sensitive data, create posts of unauthorized types, or cause denial-of-service by application crash.
