A passive DNS search found 43,601 grok.me links, and more than 35,000 opened stored app data.

Researcher Aprozper said Grok Build defaults share links to “Anyone with the link,” so a grok.me URL opened the app and its stored data. Of 43,601 links, more than 35,000 were public, including material belonging to SpaceXSI. A Cursor representative said apps stay private unless the creator shares them; Aprozper’s tests found users had to change that default. Cursor did not say whether the exposure was intentional or whether affected users will be notified.

Unconfirmed: Cursor says apps are private by default; the researcher’s tests say public sharing is the default.

Key facts
  • Users can change links to “invited users” or “only you.”
  • Lovable, Bolt, and Replit also publish DNS-visible app addresses.
  • Claude, ChatGPT, and Gemini keep link randomness in the URL path.
  • SpaceXSI data was removed after Ars asked about it.
