Summary
The Hoo Companion WordPress plugin 1.0.2 does not have any authorisation or validation checks in one of its import features, and does not sanitise the data submitted to it before storing it as the active theme's settings, allowing unauthenticated attackers to inject arbitrary web scripts which will execute for anyone viewing the site, including administrators. The same request destroys the site's existing theme settings.
