WordPress Twitter Feed Plugin 'url' Parameter Cross Site Scripting Vulnerability

Summary
The Twitter Feed Plugin for WordPress is prone to a cross-site scripting vulnerability because it fails to properly sanitize user- supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks. Twitter Feed 0.3.1 is vulnerable other versions may also be affected.
Solution
Remove Older version of Twitter Feed Plugin and Install Twitter Feed plugin version 1.0 or later. For updates refer to http://wordpress.org/extend/plugins/wp-twitter-feed
