Dimitrios Valsamaras of the Microsoft 365 Defender Research Team in a write-up  said, “Attackers could have leveraged the vulnerability to hijack an account without users’ awareness if a targeted user simply clicked a specially crafted link.”

Attackers may have abused the bug to send messages and upload videos on behalf of users. Thus leading to unauthorized exposure of private videos.
