That is only part of the CVSS scoring system. Not only do you need near-physical access (i.e. not open to the internet, already drops the rating significantly), it requires the victim to interact with a suspicious prompt, which basically drops it to the level of a phishing email (i.e. not CVSS 8.8).
This is an automatic bluetooth pairing attack. With the right equipment (which can be as simple as a Pringles can and an antenna aimed through a window) you can execute this attack from a hundred meters away. That's not physical access.
