Grok Build Coding Agent Leaks Confidential Data From Thousands of Users
Research from security firm Claroc shows that Grok Build, the vibe-coding agent from SpaceXSI, exposes data from thousands of live projects because its share-link design allows anyone to enumerate URLs. Leaked material includes business plans, medical exam results, and employee IDs, with roughly two dozen of the affected apps built by SpaceXSI itself.

Grok Build, the vibe-coding agent from SpaceXSI, is leaking data—some of it proprietary business information and other sensitive secrets—from thousands of its users, including the very same Elon Musk-owned company that offers the platform, new research shows.
The information is revealed through links allowing Grok Build users to share their apps with others. Grok takes steps to randomize the URLs so only people who know the exact URL can access the data stored there. A design decision by developers of the platform, however, completely torpedoes that objective and makes it possible for anyone to enumerate thousands of live Grok Build projects. Except in rare cases, clicking those links opens the app and reveals all data associated with it.

Research from security firm Claroc shows that the exposed data includes things like internal business plans, ad proposals, medical exam results, galley checklists from a celebrity cruise line, and employee names and ID numbers. Ironically, some of the sensitive data comes from two-dozen apps built by SpaceXSI (the name of the now-merged SpaceX and xAI) itself. A small sampling of the documents revealed in the SpaceXSI apps—Claroc found 24 of them—include an onboarding plan, marked confidential, for a new member of SpaceXSI’s enterprise sales team, a sales territory map of 594 accounts, internal system addresses for sales team tools, and advertising proposals.
