Recommendation: Monitor — no exploitation signal at the moment.

The Steveas WP Live Chat Shoutbox WordPress plugin through 1.4.2 does not sanitise and escape a parameter before outputting it back in the Shoutbox, leading to Stored Cross-Site Scripting which could be used against high privilege users such as admins.
