WordPress Pretty Link Plugin 'pretty-bar.php' Cross Site Scripting Vulnerability

The Pretty Link plugin for WordPress is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.

An attacker may leverage these issues 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.

Pretty Link 1.5.2 is vulnerable; other versions may also be affected.
