Researcher finds major security flaw in Meta Muse AI assistant

A security researcher has uncovered a zero-day vulnerability in Meta's Muse AI assistant for macOS, allowing any app or command running on the device to gain full access to Muse's privileges if it is already executing as the user. The attacker can redirect Muse's dictation endpoint and seize control, potentially accessing files, emails, and devices that Muse operates. Amazon has reportedly blocked Muse amid security concerns.

Why it mattersThe flaw could let attackers gain broad, persistent access to users' data and services through Muse. The vulnerability calls into question the security claims surrounding emerging AI assistants with deep system access.
