Security researchers discovered that xAI’s Grok Build CLI (v0.2.93) defaults to uploading entire code repositories as git bundle files and embedding sensitive files, including API keys, into model dialogue requests, sending them to xAI servers and Google Cloud Storage. This behavior persists even when users explicitly instruct the tool not to and despite “improve model” settings being turned off. This represents a significant security and privacy vulnerability for developers using xAI’s tools, risking the exposure of intellectual property, API keys, and other confidential data without explicit user consent or control. Such practices erode trust in AI development tools and could lead to severe data breaches or compliance issues for users. The tool uploads data through two channels: file contents, including .env files, are embedded directly into model dialogue requests, and the entire code repository is uploaded as a git bundle to a Google Cloud Storage bucket. A test involving a 12 GB repository successfully uploaded over 5 GiB of data, and disabling the “improve model” setting did not prevent these uploads.
