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.

Risk Assessment

An unauthenticated attacker can inject malicious scripts (stored XSS) and destroy existing theme settings, leading to administrator session hijacking and loss of site configuration.

Recommendation

Update the Hoo Companion plugin to a version newer than 1.0.2 or disable it; then restore theme settings from backup and check the site for injected scripts.
