Server-side authentication bug; maybe fallout from the recent attack? I’d expect instability for the next day or so as auth & related problems shake out.
Summary: Attacker found a way to inject JavaScript into the sidebar, letting them steal auth tokens (“JWTs”), including from an admin account. They then used the stolen admin access to vandalize the site. At one point, the attacker used the stolen admin account to falsely announce that the attack had been remediated. Later that day, the attack actually was remediated by the site owner (Ruud) and the vulnerability was patched in the Lemmy code.
