Hexbear was a victim of a targeted XSS attack similar to the attack many other Lemmy instances have seen.

The account that first leveraged the attack was registered on 2023-07-10 at 03:58 UTC, the fix for the vulnerability was applied by around 04:35 UTC. This leaves a ~40 minute window in which anyone browsing the site could have had their account hijacked.

The attacker was able to act (post, comment, DM) as the account they hijacked. They will also have been able to view/use the compromised account's settings page. This means they will have been able to see users' email addresses. Some accounts that were compromised were temporarily banned, these bans have now been lifted.

If you were using the site during the above time window, please double check your account settings to see if anything was changed.

Passwords were not stolen, JWTs were. We have just invalidated all old JWTs so the attacker no longer has access to the hijacked accounts (this is why all users have been logged out).

      I'd really like a reddit-like UI, much like the one we're currently using actually; just without JS.

          OK that's... not great but surprisingly close, and I'm very surprised it exists in the first place. Thanks !

            yeah lol. it has a dark mode even! and we could self host it in single instance mode. browsing at least works without js, didn't want to give them my login info to see if anything else did
