Meta Restores Muse Conversation Sharing After Security Concerns

What changed

Meta has re-enabled sharing for Muse conversations after security researchers reported that public conversation links could be easy to find. The researchers said they located pages containing a marketing company’s internal revenue review and a small business owner’s loan application.

Why it matters

The problem is not simply that someone shared a sensitive conversation. It is that a public link appears to have made some shared pages discoverable beyond the people who were meant to see them.

That puts a practical limit on how businesses should use Muse today. Internal financial reviews and loan applications are exactly the sort of material that can move from “useful AI workspace” to “serious exposure” when sharing controls are unclear.

Meta has restored the feature, but the reported examples make the decision consequential. Until the company’s safeguards are clearer, sharing a Muse conversation should be treated like publishing a document on the open web, not like sending a private note. The number of conversations exposed and the protections added before sharing returned remain unclear.
