Meta fixes zero-day flaw in Muse macOS app after researcher hijacks AI agent

Security researcher Patrick Wardle found an unpatched setting in Meta's Muse macOS app that let local attackers reroute the app's cloud-based dictation to their own server, effectively seizing control of the AI agent. Wardle demonstrated the flaw by using Muse's own privileges to snap photos and write files to disk, often without alerting the user. Meta issued a hotfix within hours of the report, though it maintains the exploit required existing local access and posed low real-world risk.
