CVE-2012-3383

The map_meta_cap function in wp-includes/capabilities.php in WordPress
3.4.x before 3.4.2, when the multisite feature is enabled, does not
properly assign the unfiltered_html capability, which allows remote
authenticated users to bypass intended access restrictions and conduct
cross-site scripting (XSS) attacks by leveraging the Administrator or
Editor role and composing crafted text.
