WordPress Core < 2.1.2 - 'PHP_Self' Cross-Site Scripting
source: https://www.securityfocus.com/bid/23027/info
WordPress is prone to a cross-site scripting vulnerability because the application 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. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
