Surely this exploit proves that it’s best to minimise the number of administrative actions available in the UI?

I’m not particularly familiar with XSS but I’m curious how a frontend exploit can compromise an instance?

Presumably the injected XSS stores the admin’s JWT somewhere for the exploiter?

Then using that JWT they can effectively login as the admin which gives them access to whatever admin dashboard there is, but does that actually compromise the backend at all?

edit: for anyone curious there’s a bit of a breakdown of how it works here: https://feddit.win/comment/244427
