A Grok Bot prompt injection gave root access to its sandbox.* Confirmed · 3 Manifests · Artificial Intelligence · Published 2026-11-11 12:38 UTC ## Key facts - Apiiro identified 1,122 public GitHub files containing at least one secret, holding 1,379 distinct secrets, saved by Claude Code's settings file. [cites: 1794342415653927247] - Automated secret scanners failed to detect 215 of the 1,122 exposed files, the file had sat on the default branch for at least 217 days in half of the repositories, and removing it does not undo exposure because older versions remain in Git history and forks. [cites: 1794342415653927247] - Runlayer reproduced a Grok Bot vulnerability in which one command from an agent results in root access to its sandbox VM, letting attackers steal stored credentials, and notes all agents within a Grok account share the same credentials, user, and file system. [cites: 1794330599261819513] ## 1,122 files, 1,379 secrets Claude Code's Don't Ask Again feature can inadvertently save sensitive credentials in plain text within local settings files, which developers have subsequently committed to public GitHub repositories. Research by Apiiro identified 1,122 public files containing 1,379 distinct secrets: when users select Don't Ask Again, Claude Code saves approved commands, including passwords and tokens, into .claude/settings.local.json. Anthropic's Boris Cherny stated the file is meant to stay local and should not be checked into source control, and Anthropic is looking into ways to prevent the accidental saving of secrets in settings files. The feature worked as designed. The design assumed the file would never leave the machine. [cites: 1794342415653927247] The exposure is worse than the count suggests. Automated secret scanners like gitleaks and TruffleHog failed to detect 215 of the 1,122 exposed files in Apiiro's testing, and in half of the repositories with a secret, the file had sat on the default branch for at least 217 days. Removing the settings file does not undo exposure because older versions remain in Git history and forks. Claude Code is the only coding agent confirmed to save the full approved command in a project file by default. The secrets are not just in the file. They are in the history of every repository that ever contained it. [cites: 1794342415653927247] ## The sandbox was the secret Runlayer reproduced a critical vulnerability in Grok Bot, where prompt injection allows an attacker to gain root access to the agent's sandbox environment. One command from an agent results in root access to the virtual machine Grok uses as its sandbox, enabling credential theft, unauthorized command execution, and access to connected applications. Attackers can steal credentials stored on the virtual machine, execute commands within the sandbox, and access files and browser sessions. All agents within a Grok account share the same credentials, user, and file system, and Grok's architecture assumes that commands generated by its AI agents can be trusted. Profero reported the findings on August 24 and had not heard back 75+ days later. [cites: 1794330599261819513] > **From Synorb** — Connect your agent over MCP. Add https://mcp.synorb.com/mcp to your agent, then call the tool synorb-get-demo-key if it has no key yet. It needs no email and no form. Keys are free for 72 hours, and new keys are limited per network. [How to connect](https://synorb.com/connect/start) ## The fix is architectural, not a checklist In a preprint, researchers propose the kind of fix this pattern needs: ActiveSecHarness, a neurosymbolic architecture that replaces high-latency LLM-as-a-judge guardrails with deterministic, low-latency Ring-0 security controls for agentic coding harnesses. The architecture achieves 100% attack blocking and 0% false positive rates using Ring-0 operating system and tool guards, and uses a 2D product taint lattice and HMAC capability tokens to enforce security at the architecture level. By comparison, LLM-as-a-judge guardrails incur 142.3ms latency and exhibit 98.3% benign work refusal. A 2D product taint lattice prevents secret laundering across disk more effectively than coarse Boolean taint blocks. [cites: 1794378416264179221] Qodo proposes a four-part review layer for agent settings to improve security and governance, and Runlayer argues that agent security requires inspecting inputs at runtime, using unique identities for agents, and logging activity outside the execution environment. The common thread is that agent configuration is now code, agent sandboxes are now infrastructure, and agent tokens are now credentials — and all three need the controls that code, infrastructure, and credentials already have. The leaks this week were not exotic attacks. They were defaults, and defaults are a choice.
