The plugin does not properly some of its settings, which could allow high-privilege users to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disallowed (for example in multisite setup), and we consider it a low risk.

1. In the Kofi plugin settings, change the "Button Text" field to: `<img src=x onerror=alert(1)>`
2. Add the [kofi] tag to one of your pages
3. View that page and see the XSS
