The plugin does not properly sanitize 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)

PoC

1. Add XSS payload to plugin’s “Account API key” setting: "> 2. Save and see XSS exploit.
