Muse Ships With A Zero-Day

The Signal · 2026-09-22

Meta sold Muse on privacy and security. Ars Technica reports the assistant shipped with a serious zero-day. Muse is extraordinarily privileged, so one bug reaches far: a single flaw in an agent with deep access carries a much bigger blast radius.

Also today: Appfigures estimates Muse has passed ChatGPT's early mobile downloads and daily active users in the US and Canada.

California signed seven laws tightening AI data center energy and water use. Operators are barred from shifting utility costs onto residents.

That's today's Signal. Thanks for watching.
