While I was asleep, apparently the site was hacked. Luckily, (big) part of the
lemmy.world team is in US, and some early birds in EU also helped mitigate this.
As I am told, this was the issue: - There is an vulnerability which was
exploited - Several people had their JWT cookies leaked, including at least one
admin - Attackers started changing site settings and posting fake announcements
etc Our mitigations: - We removed the vulnerability - Deleted all comments and
private messages that contained the exploit - Rotated JWT secret which
invalidated all existing cookies Because not all instances are aware, we will
not go into detail on the vulnerability yet. Many thanks for all that helped,
and sorry for any inconvenience caused!
