A vulnerability has been discovered in the SoundCloud Is Gold plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "width" POST parameter in wp-admin/admin-ajax.php (when "action" is set to "soundcloud_is_gold_player_preview" and "request" is set to "1") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is confirmed in version 2.1. Other versions may also be affected.
