    GitHub PR fixing the bug: https://github.com/LemmyNet/lemmy-ui/pull/1897/files

    If your instance has custom emojis defined, this is exploitable everywhere Markdown is available. It is NOT restricted to admins, but can be used to steal an admin’s JWT, which then lets the attacker get into that admin’s account which can then spread the exploit further by putting it somewhere where it’s rendered on every single page and then deface the site.

    If your instance doesn’t have any custom emojis, you are safe, the exploit requires custom emojis to trigger the bad code branch.

      But won’t custom emojis from remote instances still trigger the exploit?

        Apparently the custom emojis are rendered as static images when federated to outside instances so it’s clean.

    Yea, I switched to this alt. It appears to be one of the assistant admins accts. Seems like an old fashioned anon prank, to me, they’re mainly just trying to make stuff offensive and redirect people to lemonparty.

    So, y’know, old school.

    I don’t know if any data is actually in danger, but I doubt it. I don’t see why assistant admins would need access to it.

      All the bean memes are in danger! On a serious note, old-skool or not, it’s a huge loss of trust in something the community-at-large is excited to see replace reddit.

          True that. If you look at posts on lemmy.world though, it’s clear their users (which is like 50% of Lemmy) have zero clue they’re defederated ATM, and probably many that don’t know it’s compromised.

            Federation and decentralization are not Web 2.0 concepts. Just like people who first learned what a tweet and a follow were and all the other concepts of those social media platforms, they’ll learn the new paradigm. Or they won’t and we’ll stick to 2.0 platforms.
