Microsoft Edge (Chromium-based) Tampering Vulnerability

How could an attacker exploit this vulnerability via the Network?
An attacker could host a specially crafted website designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action, typically by an enticement in an email or instant message, or by getting the user to open an attachment sent through email.

According to the CVSS metrics, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L)? What does that mean for this vulnerability?
Information in the victim's browser associated with the vulnerable URL can be read by the malicious JavaScript code and sent to the attacker.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?
The user must visit the attacker‑controlled webpage, and perform the two tap gestures that cause autofill to activate.
