A researcher says a flaw in Meta's Muse app for Mac lets any app or terminal command gain access to the token that authenticates users to their Muse account (Dan Goodin/Ars Technica)

A reported flaw in Meta’s Muse Mac app could allow any local app or terminal command to access the authentication token for a user’s Muse account, creating a serious account-takeover and data-exposure risk. For CIOs and IT leaders, this underscores that AI assistants and productivity apps can introduce new identity and token-security vulnerabilities that bypass traditional perimeter controls, making endpoint hardening, app trust validation, and AI usage governance increasingly important. The business impact is potential leakage of sensitive prompts, outputs, and connected account data, along with reputational and compliance risk if such tools are deployed broadly without proper controls.
