Formatting URL in Security Settings
The first URL will allow any link to that specific subdomain of mural.co.
The second URL allows traffic to any and all Eventbrite sites, including www.eventbrite.com, eventbrite.com, eventbright.com.au, eventbrite.de, etc.
This whitelist is checked, even when the "Warn users" toggle is off, in the case of a widget (like the events widget) not respecting the toggle.
