This issue is already quite widely publicized and quite frankly “we’re handling it and removing this” is a much more harmful response than I would hope to see. Especially as the admins of that instance have not yet upgraded the frontend version to apply the urgent fix.
It’s not like this was a confidential bug fix, this is a zero day being actively exploited. Please be more cooperative and open regarding these issues in your own administration if you’re hosting an instance. 🙏
IMO it’s not a good idea to be discussing attack vectors publicly when a number of other instances are unpatched and the exploit has been in the wild for less than a day.
I agree that admins need to work together, but discussing it in public on Lemmy so soon after the attack isn’t the way. There exists a Matrix channel for admins, that’s where this type of thing should go.
