JSON GET APIs are vulnerable to being embedded as JavaScript when the Array prototype has been patched to track data. Checks the referrer even on GET requests if the content type is JSON.

If request includes Origin HTTP header, defers to HttpOrigin to determine if the request is safe. Please refer to the documentation for more info.
