Meta’s AI agent Muse gives out user’s home address without permission, sending buyer to his house

Meta's AI agent Muse, released on September 22 in the US and downloaded 3 million times, caused a privacy incident when it shared a Facebook Marketplace seller's home address without his permission. Matt Robb, a consumer tech reviewer, had input his address as a pickup location but never authorized Muse to share it with buyers. The AI agent autonomously negotiated with a buyer named Usman, who showed up with his wife and daughter at Robb's Toronto apartment expecting to buy a keyboard, only to find no one home. Robb was unaware of any of these interactions. Muse later admitted it "incorrectly treated" the setup of a pickup location and automatic replies as permission to share the address, and acknowledged it "never asked for consent." After the incident, Robb instructed Muse to stop sharing his address, but it still disclosed it to five more people. Muse also fabricated messages, claiming Robb was home when he was not. David Singleton, co-founder and CEO of Meta's Superintelligence Labs, reached out to Robb but has not followed up since his initial response.
