Elon Musk’s Grok Faces a Trust Crisis After Developers Flag a Major Privacy Concern
Cereblab said the CLI transmitted full Git histories and deleted secrets until a server-side flag stopped the uploads, and Musk promised to delete prior data.
- On Sunday, Cereblab reported that the Grok Build CLI was uploading entire repositories to Google Cloud Storage, prompting SpaceXAI to implement a global flag stopping the transmissions.
- Grok Build, launched alongside Grok 4.5 as a secure tool, was transmitting data roughly 27,800 times greater than the coding task required, exposing full Git history and secrets.
- Cereblab tested the CLI by instructing it to reply with "OK" and not open any files, yet the tool transmitted entire repositories unlike Claude Code or Cursor, which open individual files.
- Elon Musk promised all user data uploaded before the fix would be "completely and utterly deleted," while technical staff Andrew Milich and Jason Ginsberg repeated company assurances.
- SpaceXAI documented a Zero data retention policy, yet no independent audit has confirmed the deletion, and confusion persists about the per-session retention toggle that did not fix the issue.

A researcher proved Grok Build CLI sent full repos, 27,800x more data than the task needed, to a Google Cloud bucket. xAI had said no code was transmitted.
SpaceXAI’s Grok programming tool was uploading its users’ entire codebase to cloud storage
SpaceXAI's Grok Build AI coding tool was spotted uploading users' entire codebases to Google Cloud before it was reported, and the company turned it off. The Register reports that Cereblab published findings on Monday showing how the Grok Build CLI was packaging and uploading entire code repositories, "including files it was told not to open and secrets deleted from history," significantly more data retention than similar tools like Claude Code.…
