  - wp-admin/user-new.php sets the newbloguser key to a string that can be directly derived from the user ID,
which allows remote attackers to bypass intended access restrictions by entering this string. (CVE-2017-17091)

  - wp-includes/functions.php does not require the unfiltered_html capability for upload of .js files,
which might allow remote attackers to conduct XSS attacks via a crafted file. (CVE-2017-17092)

  - wp-includes/general-template.php does not properly restrict the lang attribute of an HTML element,
which might allow attackers to conduct XSS attacks via the language setting of a site. (CVE-2017-17093)

  - wp-includes/feed.php does not properly restrict enclosures in RSS and Atom fields,
which might allow attackers to conduct XSS attacks via a crafted URL. (CVE-2017-17094)");
