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 "GigPress > Settings"
2. Enter the payload `"><script>alert(1)</script>` in the "Artist Label" field"
3. Click "Save Changes" and see XSS
4. Other fields may also be vulnerable
