Meta restores Muse sharing after fixing the DNS-related exposure
Meta says it fixed the issue that made Muse share addresses discoverable through passive DNS records and has restored sharing; older artifact links were replaced with new URLs.
AT A GLANCE
Key points
- Meta has restored Muse sharing.
- The issue was tied to URLs for shared document and image artifacts.
- Artifacts shared before the fix received new URLs.
- Old links now tell visitors to request an updated address from the owner.
What is changing?
Meta restored the sharing feature in its personal AI agent Muse on October 22. The company had temporarily paused it after Claroc researchers found more than 6,800 share hostnames containing conversation titles in passive DNS records.
Meta executive David Singleton said the underlying issue had been fixed and sharing was back on. According to his statement, the problem was not with all conversation sharing but with the URL structure for shared Muse artifacts such as documents and images.
Artifacts shared before the fix were assigned new URLs. People who open an older link will see a note asking them to get the updated address from the owner. Meta acknowledged the disruption and said protecting user data took priority.
Claroc’s research showed that long, difficult-to-guess tokens were not sufficient when titles were written into subdomains. No independent technical audit of the revised design has been published, so the scope of the fix currently relies on Meta’s account.
