Yes and no. XSS vulnerabilities are a plentiful problem when there's user generated content and many developers. But this specific exploit targetted the markdown renderer interacting with custom emoji, which I don't think is a feature kbin has?

This is a good question. From what’s been released so far it looks like attackers were able to remotely steal authentication tokens, which are normally stored securely in your browser. With these authentication tokens, the attackers were able to access user data, and even in some cases they were able to take over administrator accounts.
From the post that Admin‘s made after the breach was fixed it looks like they spent some time trying to clean up the damage that was done. From what I can see they cleaned up most of the obvious stuff. That said there’s probably a long tail of smaller stuff that they missed that. Still hanging around out there if you notice something report it to an admin.
Just to add, as a user once you logout and login again this will kill the old token and issue a new one. This will stop an attacker who has stolen your token from accessing your account.
As for impact, it really depends on what data you have in your account. Assuming you are a heavy shitposter and do not store nuclear secrets in your account, the impact should be minimal.
I wish that was an assumption we could make. How many other remfie nat guardsmen are holding classified shit to post for internet clout?
How many ex presidents do we have on Knin?
I don't think there's any risk of someone stealing your kbin account with this, however I do think that admins can access more data than normal users, including from federated instances. They where only logged in on the web, and I think you can only access that kind of data by accessing the database more directly, which the exploit wouldn't have allowed the hackers to do.
