A GitHub issue with zero repo privileges can run code on Anthropic and Google CI runners — Black Hat 2026 tears apart coding agent trust
On August 5, 2026, Novee Security demonstrated at Black Hat USA that a GitHub issue opened by an account with no write access was enough to execute arbitrary code on the CI runners behind Claude Code, Gemini CLI, and OpenAI Codex repositories. If your CI/CD pipeline executes code from GitHub issues without sandboxing, treat this as a CVE with no patch — yet.
