Interesting question, is this a UAC bypass? My first thought is no, because UIPI means you can't automate the interaction. Therefore, the only way to exploit it is if you could have just clicked OK in the UAC consent anyway.... right? (yes, I know UAC is not a supported boundary)https://twitter.com/harr0ey/status/1211075032400760832 …
This is not a UAC bypass. Look here for another example:https://twitter.com/z3roTrust/status/1174998670342836224?s=19 …
