Summary

The MCB Stats WordPress plugin, through version 1.0.0, fails to sanitise User-Agent request header values before storing them and displaying them in the administrator statistics grid. An unauthenticated attacker can store malicious JavaScript this way, which runs in an administrator's browser when that person views the statistics page.
