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 no loss of confidentiality (C:N), some loss of integrity (I:L) but have no effect on availability (A:N). What is the impact of this vulnerability?
An attacker using either a specially-crafted page or a content script injected into a target page can show an extension's popup over a permission prompt or screen share dialog allowing the extension to spoof parts of the prompt's UI that shows its origin.
