WordPress Plugin Comment Rating 2.9.20 - 'path' Cross-Site Scripting

source: https://www.securityfocus.com/bid/51241/info

The Comment Rating plugin for WordPress is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input.

An attacker could leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This could allow the attacker to steal cookie-based authentication credentials and launch other attacks.
