Meta Pauses Feature After Bug Let Others See Chats with Muse

Due to a flaw in the design of links for sharing conversations, users' private chats with Meta's AI assistant Muse could have been accessible to parties they were not intended for, so the company is temporarily disabling this feature.

✨ What happened

Meta is temporarily disabling a feature that allowed users to share links to conversations with the Muse AI assistant. The reason is that security researchers found that it was far too easy to access sensitive information that users shared with the assistant.

People could ask the assistant questions about personal matters and then send a link to their conversation to someone else. Due to a flaw in the settings, such a link could open that conversation not only to the person it was sent to.

📌 Why it matters

Many people believe that a chat with an AI assistant is like a private conversation. So they may write about health, money, relationships, or work without thinking about who else might see it.

This story shows that even a convenient feature like a “share” button can create a privacy risk. Before sharing a link to a chat, it is worth checking who will be given access to it and not sending personal data unless necessary.
