lemmy.world is a victim of an XSS attack right now and the hacker simply injected a JavaScript redirection into the sidebar. It appears the Lemmy backend does not escape HTML in the main sidebar. Not sure if this is also true for community sidebars. [https://sh.itjust.works/pictrs/image/707c0f16-3d5c-4888-b865-34228d968ee6.png]

Both lemmy.world and lemmy.blahaj.zone are both down, this issue IS URGENT as this could be why they are both down.

also yes I didn’t receive a notif.
