CVE-2018-20148 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. CVE-2018-20149 When the Apache HTTP Server is used, authors could upload crafted files that bypass intended MIME type restrictions, leading to XSS, as demonstrated by a .jpg file without JPEG data. CVE-2018-20150 Crafted URLs could trigger XSS for certain use cases involving plugins. CVE-2018-20151 The user-activation page could be read by a search engine's web crawler if an unusual configuration were chosen. The search engine could then index and display a user's e-mail address and (rarely) the password that was generated by default. CVE-2018-20152 Authors could bypass intended restrictions on post types via crafted input. CVE-2018-20153 Contributors could modify new comments made by users with greater privileges, possibly causing XSS. For Debian 8 "Jessie", these problems have been fixed in version 4.1.25+dfsg-1+deb8u1. We recommend that you upgrade your wordpress packages.
