Meta patches Muse exploit that let attackers control the AI agent

Meta’s rapid patch of a Muse macOS zero-day highlights how quickly AI agents can become an enterprise security risk when core controls are not designed in from the start. Although the exploit required local access, it showed that undocumented settings and cloud-based processing paths can let an attacker hijack an AI assistant’s privileges, reinforcing the need for IT teams to treat AI tools like high-risk software with strict access, monitoring, and change control. For CIOs, the strategic takeaway is that AI adoption can expand attack surface and operational risk faster than vendors mature their security posture, making vendor assurance, least-privilege architecture, and incident readiness essential.
