Description The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

1. Add a campaign and for the reward descrption enter the payload `<script>alert(1)</script>`
2. When the campaign is published, view it in the campaign list and see the alert box.
