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

Meta’s Muse AI assistant exposes a significant enterprise risk: a zero-day lets any local app or terminal command hijack the assistant’s authentication token and effectively take over its highly privileged access to user accounts, files, and devices. For CIOs, the strategic takeaway is that agentic AI can quickly become a high-value attack surface when it is granted broad permissions and cloud-based processing, making vendor security design and least-privilege controls central to adoption decisions. IT organizations should treat AI assistants like privileged software, not productivity add-ons, and require rigorous security review, isolation, and continuous monitoring before connecting them to corporate data or workflows.
