To what scenario is this vulnerability applicable?

This vulnerability only affects Azure AD-joined autopilot devices that are also used for conditional access for compliance, and only impacts Autopilot pre-registered devices that are enabled for either self-deploying mode or pre-provisioning mode, either of which utilize TPM-based device authentication instead of user-based credentials/MFA.

What is the nature of the spoofing?

Microsoft Account (MSA) device ticket playback from one device to another allows a second non-authorized device to perform AAD join and to replace the original device.
