Security researcher Armin Ebert reported that the location.host property can be set to an arbitrary string after creating an invalid data: URI. This allows for a bypass of some same-origin policy protections. This issue is mitigated by the data: URI in use and any same-origin checks for http: or https: are still enforced correctly. As a result cookie stealing and other common same-origin bypass attacks are not possible.
