According to [**this writeup**](https://blog.geekycat.in/google-vrp-hijacking-your-screenshots/), if you can iframe a webpage without X-Frame-Header that contains another iframe, you can **change the location of that child iframe**.
For example, if abc.com have efg.com as iframe and abc.com didn't have X-Frame header, I could change the efg.com to evil.com cross origin using, **`frames.location`**.
This is specially useful in **postMessages** because if a page is sending sensitive data using a **wildcard** like `windowRef.postmessage("","*")` it's possible to **change the location of the related iframe (child or parent) to an attackers controlled location** and steal that data.
