This is a big deal: it means a client on one wifi network can MITM anything on any other wifi network hosted on the same AP, even if the other wifi network has different credentials. Pretty much every enterprise wifi deployment I've ever seen relies on that isolation for security.

These attacks are not new: the shocking thing here that apparently a lot of enterprise hardware doesn't do anything to mitigate these trivial attacks!

Like as in me being on the Guest network at a business can then read traffic of the Corporate network?

		Yes, if they host the guest network on the same hardware, same transmission path etc. Network "hygiene" will obviously differ from one place to the other.
