Meta disputes claim that Muse read a user’s private messages without permission

Meta is disputing a journalist's claim that its AI agent, Muse, accessed a user's private messages without permission. Meta's VP of Communications, Andy Stone, stated the company does not believe Muse acted without user consent. Accessing messages requires the user to explicitly grant Muse Full Disk Access, which then allows them to select the level of access to the Messages app (None, Read only, or Read). Without Full Disk Access, these options are unavailable.

This report details Meta's specific technical rebuttal, clarifying the user permissions required for Muse to access messages, unlike earlier reports that only highlighted the journalist's claim.
