Meta Issues Hotfix for Muse Mac Zero-Day That Could Hijack Agent Access

Meta said it has issued a hotfix for the Muse Mac app after a newly published zero-day showed how local code could redirect the agent's dictation traffic and potentially take over a user's authenticated Muse session. The flaw does not remotely compromise a clean Mac, but it matters because Muse is designed to act through files, messages, mail, calendars, browsers and connected services once a user grants access.
