CVE-2026-12537 is an improper neutralization of OS command elements vulnerability in the Google Gemini CLI container launcher and the run-gemini-cli GitHub Action. In affected headless CI environments, attacker-controlled workspace configuration and environment-variable content can reach command execution before the container sandbox is established. The issue affects Gemini CLI releases before 0.39.1, including the affected preview release line before 0.40.0-preview.3, and run-gemini-cli releases before 0.1.22.

An OS command injection vulnerability in Gemini CLI's container launcher that can allow an unprivileged attacker to execute code on the host of a headless CI platform before the sandbox starts.
A critical remote code execution vulnerability in Google Gemini CLI and its related GitHub Action caused by improper workspace trust handling in headless CI environments and allowlist bypass behavior in --yolo mode, enabling arbitrary command execution in CI/CD pipelines processing untrusted input.
A critical unauthenticated remote code execution vulnerability in Google Gemini CLI and the run-gemini-cli GitHub Action that allows pre-sandbox host-level code execution on headless CI platforms via a malicious .gemini/.env file.
A remote code execution vulnerability in Gemini CLI workspace-trust and tool-allowlisting behavior. In headless CI environments, untrusted workspace configuration or environment variables could be processed automatically; additionally, --yolo could ignore a configured fine-grained allowlist, enabling prompt-injection-driven arbitrary shell-command execution.
