CVE ID         : CVE-2018-20147 CVE-2018-20148 CVE-2018-20149

Debian Bug     : 916403


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.
