Meta re-enabled sharing on its Muse AI assistant after temporarily disabling it when security researchers found that shared conversation links were predictably named and discoverable via public DNS records. Meta executive David Singleton said the flaw affected URLs for shared 'artifacts' like documents and images, not chat sharing itself, and has now been fixed. Previously shared artifact links have been invalidated and given new URLs, requiring users to re-share them.

After users discovered yesterday that Meta's Muse AI chatbot would reveal its underlying filesystem when prompted, Meta executives clarified this was deliberate design rather than a leak. Meta Superintelligence Labs' David Singleton said each Muse session runs on a genuine cloud-based Linux virtual machine users can operate freely, and the product now offers a clickable file browser with root access instead of yesterday's more limited text-file download.

Security researcher Patrick Wardle disclosed a zero-day vulnerability in Meta's Muse AI agent that could let attackers redirect users' voice dictations and access tokens to a malicious server instead of Meta's own. David Singleton, head of Meta's Superintelligence Labs, confirmed the company has issued a patch, though he and Wardle disagree on whether the exploit requires prior malware on a user's machine. Meta says the MacOS Muse app has been downloaded over half a million times in its first week.

A journalist testing Meta's Muse AI assistant on its new Mac app found it referencing contents of his Messages conversations, despite believing he hadn't granted access. When questioned, Muse gave a confused and inaccurate explanation, claiming it only saw notification previews synced through the paired Mac app. Meta executive David Singleton later clarified that Muse only accesses Messages data after a user explicitly opts in, and that the assistant's own explanation of its capabilities was simply wrong.
