Meta re-enables Muse artifact sharing with new URLs

Meta has turned Muse artifact sharing back on after researchers at Claroc found that public links to shared documents and images were derived from conversation titles and exposed via public DNS. Old links now show a note asking visitors to request a new URL from the owner.

• Claroc researchers found internal company documents exposed through Muse share links
• Meta paused sharing after Ars Technica's inquiry and says the issue is now fixed
• Previously shared artifacts received new URLs; old links no longer resolve
• Meta says the flaw affected artifacts, not chat sharing itself
