OVERVIEW

        Multiple vulnerabilities have been fixed in WordPress 3.4.1.[1]


IMPACT

        The following information is available on the WordPress website:
        
        " * Privilege Escalation/XSS. Critical. Administrators and editors in
            multisite were accidentally allowed to use unfiltered_html for
            3.4.0.
        
          * CSRF. Additional CSRF protection in the customizer.
        
          * Information Disclosure: Disclosure of post contents to authors and
            contributors (such as private or draft posts).
        
          * Hardening: Deprecate wp_explain_nonce(), which could reveal
            unnecessary information.
        
          * Hardening: Require a child theme to be activated with its intended
            parent only." [1]
