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. Go to https://example.com/wp-admin/admin.php?page=amen-options
2. Enter the payload: `"><script>alert(1)</script>` for the "Submission & Management"
3. Save the setting and see the XSS

Note: Other fields are likely vulnerable
