Hi everyone.

Lemmy had an XSS vulnerability and we were one of the instances attacked through this vulnerability. We had our homepage replaced by a youtube video.

The lemmy devs were quick to create a PR for this issue and we have patched our instance to fix it,

Also while I do not believe any login tokens were compromised, we have taken the additional measure of rotating our secret key, so everyone will have to login to the site again as your existing credentials will no longer be valid.

If login fails to work properly, you may have to clear your cookies for the site… it seems to get confused about whether you’re logged in or not.

Sorry that this happened, if you have any questions please contact @[email protected] or myself.

blobcat, heart

    I can no longer access my blahaj account, which sucks because ive done alot on it. Im not sure if its because Blahaj is down or my account is gone, I just cant get into my account anymore.

        I’m having the same issue. I can’t access the website at all and I definitely cannot login on my app (Connect). I’ve cleared my cookies several times and tried to access the page to no avail.

        I’m facing the same issue. I tried disabling JS by setting Blåhaj Lemmy to “untrusted” on NoScript, and this seemed to work the first time I tried it, but not any subsequent times.

        The message I see is, “There was an error on the server. Try refreshing your browser. If that doesn’t work, come back at a later time. If the problem persists, you can seek help in the Lemmy support community or Lemmy Matrix room.”

        Opening up the split console in Firefox Web Developer Tools, I see “500 Internal Server Error”. Comparing and contrasting with lemmy.world, I don’t see any other meaningful difference. I’ve also tried visiting Blåhaj Lemmy on Google Chrome on my Android phone, where I don’t have any extensions, but that gave me the same error message.

    Damn that was quick! I didn’t even notice LOL if it wasn’t for this post I would have thought that my account got logged off just for a bug :p

      By the way, I don’t know if this is related but I have an issue now after this

      I can log in using the web app but in Jerboa when I log in I can see Im logged in but I when I try to do something like commenting it tells me I’m not, then after reopening the app I’m fully logged off again, has this happened to someone else?

        you gotta sign out the master key used to authenticate your session was cycled, so you need to get a new one, jerboa gets confused cuz it already has one but is no longer valid

          Ohhh it works now! Since it said I wasn’t logged in I thought that meant I wasn’t logged in but apparently not :p

        The master encryption key was rotated, meaning your current login creds/tokens are invalid and you have to login again.

      Well, I don’t technically work on the lemmy codebase (I have my hands full with adminning 3 instances and working on Hajkey), but yes I agree it’d be nice if the lemmy dev team could spend some time reviewing and improving the security, in amongst all the other stuff they have to do since Reddit imploded.

    Something still seems broken on the home page. Multiple browsers, clearing cookies, private mode, etc have the same error message. Voyager is also unable to log in. Memmy working ok.

    Home page and almost every link from the home page look the same.

      Sorry about this. It was caused by an erroneous emojo making the site info endpoint fail to load. Issue is fixed now.

    Fittingly, given that the hack seemed to be through the custom emoji interface (?), this thread has some wonderful emoji action!!

    What sort of YouTube video replaced the home page? I’m assuming it was some sort of shock/racist content.
