If an attacker can control a script that is executed in the victim's browser, then they can typically fully compromise that user. Amongst other things, the attacker can:
Perform any action within the application that the user can perform. View any information that the user is able to view. Modify any information that the user is able to modify. Initiate interactions with other application users, including malicious attacks, that will appear to originate from the initial victim user.
