“Basically, I'm going to keep talking to you, but I’m going to disappear," longtime security researcher Katie Moussouris told me in a private Clubhouse room in February. “We'll still be talking, but I'll be gone.” And then her avatar vanished. I was alone, or at least that's how it seemed. “That’s it," she said from the digital beyond. "That's the bug. I am a fucking ghost.”

It's been more than a year since the audio social network Clubhouse debuted. In that time, its explosive growth has come with a panoply of security, privacy, and abuse issues. That includes a newly disclosed pair of vulnerabilities, discovered by Moussouris and now fixed, that could have allowed an attacker to lurk and listen in a Clubhouse room undetected or verbally disrupt a discussion beyond a moderator's control.
