multiple vulnerabilities.");

"According to its self-reported version number, the WordPress
application running on the remote web server is prior to 4.5.3.
It is, therefore, affected by the following vulnerabilities :

  - An unspecified flaw exists in the Customizer component
    that allows an unauthenticated, remote attacker to
    perform a redirect bypass.

  - Multiple cross-site scripting vulnerabilities exist due
    to improper validation of user-supplied input when
    handling attachment names. An unauthenticated, remote
    attacker can exploit these issues, via a specially
    crafted request, to execute arbitrary script code in a
    user's browser session.

  - An information disclosure vulnerability exists that
    allows an unauthenticated, remote attacker to disclose
    revision history.

  - An unspecified flaw exists in oEmbed that allows an
    unauthenticated, remote attacker to cause a denial of
    service condition.

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to remove categories
    from posts.

  - An unspecified flaw exists that is triggered when
    handling stolen cookies. An unauthenticated, remote
    attacker can exploit this to change user passwords.

  - Multiple unspecified flaws exist in the
    sanitize_file_name() function that allow an
    unauthenticated, remote attacker to have an unspecified
    impact.

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
