  script_tag(name:"insight", value:"CVE-2018-20147

Authors could modify metadata to bypass intended restrictions on deleting files.

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.
