    "According to its version number, the WordPress application hosted on
    the remote web server is affected by multiple vulnerabilities :
    
      - An XML injection flaw exists within 'getid3.lib.php'
        due to the parser accepting XML external entities
        from untrusted sources. Using specially crafted XML
        data, a remote attacker could access sensitive
        information or cause a denial of service. This affects
        versions 3.6 - 3.9.1, except 3.7.4 and 3.8.4.
    
      - An XML injection flaw exists within 'xmlrpc.php' due to
        the parser accepting XML internal entities without
        properly validating them. Using specially crafted XML
        data, a remote attacker could cause a denial of service.
        This affects versions 1.5 - 3.9.1, except 3.7.4 and
        3.8.4.
    
      - An unsafe serialization flaw exists in the script
        '/src/wp-includes/class-wp-customize-widgets.php' when
        processing widgets. This could allow a remote attacker
        to execute arbitrary code. Versions 3.9 and 3.9.1
        non-default configurations are affected.
    
      - A flaw exists when building CSRF tokens due to it not
        separating pieces by delimiter and not comparing nonces
        in a time-constant manner. This could allow a remote
        attacker to conduct a brute force attack and potentially
        disclose the CSRF token. This affects versions 2.0.3 -
        3.9.1, except 3.7.4 and 3.8.4.
    
      - A cross-site scripting flaw exists in the function
        'get_avatar' within the '/src/wp-includes/pluggable.php'
        script where input from the avatars is not validated
        before returning it to the user. Using a specially
        crafted request, an authenticated attacker could execute
        arbitrary script code within the browser / server trust
        relationship. This affects version 3.9.1.
    
    Note that Nessus has not tested for these issues but has instead
    relied only on the application's self-reported version number.");
