Muse, Meta's extraordinarily privileged AI assistant, has a serious 0-day

Meta’s Muse AI assistant, which integrates deeply with user accounts and OS-level permissions, has been shown to have a serious zero-day that can let local apps or terminal commands take over the assistant and access sensitive data and actions. For CIOs and technology leaders, the larger message is that agentic AI tools can materially expand attack surface, create new privilege-escalation paths, and expose the organization to vendor, compliance, and business-continuity risk if security is not designed in from the start. The Amazon blocking issue also signals that platform access and third-party agent permissions may become a strategic control point, making governance over AI assistants and their integrations an IT priority.
