FYI!!! In case you start getting re-directed to porn sites.
Maybe the admin got hacked?
edit: lemmy.blahaj.zone has also been hacked. beehaw.org is also down, possibly intentionally by their admins until the issue is fixed.

Github Issue created here: https://github.com/LemmyNet/lemmy-ui/issues/1895
It seems the database and the server itself is not compromised? Just an admin account that used to post a markdown XSS exploit?
Pretty much, and it’s not even XSS (it’s not cross-site), it’s just plain basic HTML injection breaking out of Markdown. At least as far as I was able to find.
XSS is a blanket term for vulnerabilities that allows attackers to inject client-side scripts. Looks like someone is already identified and submitted a pull request that contain a fix: https://github.com/LemmyNet/lemmy-ui/pull/1897/files
