We have little information currently, but we may at least lock the site down for preemptive safety reasons. There seems to be a serious XSS vulnerability within lemmys code. We have disabled community creation temporarily and are contemplating taking the site down temporarily as well. Please find us below and stay safe, ya'll.

EDIT: For the time being we have disabled federation, new user sign ups, and community creation.

Thanks for the heads up! Sounds serious. Keeping fingers crossed that it will get fixed quickly.

Good luck. The real problem is that bugs like this in your code that lead to easy XSS script loads like this tend to point to a bigger problem.

I agree. There needs to be an audit of lemmy entire source.

This is on top of the privacy concerns and huge potential for vote manipulation.

What are these concerns and are they unique to Lemmy vs other fediverse type software like Mastodon?

The issue seems resolved according to lemm.ee
