Answer in brief
CVE-2026-12537 records a Critical severity (CVSS 10.0) vulnerability in Unauthenticated Remote Code Execution in Gemini CLI CI/CD Workflows. The current sources do not mark it as known exploited. The current feed maps Google Cloud/Gemini CLI (generic), Google Cloud/run-gemini-cli GitHub Action (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 10.0. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Improper Neutralization used in an OS Command in the container launcher in Google Gemini CLI (versions prior to 0.39.1) and run-gemini-cli GitHub Action (versions prior to 0.1.22) on headless CI platforms allows an unprivileged attacker to achieve pre-sandbox host-level code execution a maliciously crafted .gemini/.env file.
