Description
The Discussion Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the user profile Website field in all versions from 2.2.1 up to, and including, 2.6.0, due to insufficient output escaping of the user URL when the plugin builds reply author links for discussion topics. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that will execute whenever a user views a discussion topic that contains a reply by the attacker.
