OpenAI has open-sourced @openai/codex-security, a CLI and TypeScript SDK designed to identify, validate, and remediate security vulnerabilities in code. This tool allows users to scan repositories, review changes, track findings, and integrate security checks into their CI pipelines. It requires Node.js 22+, Python 3.10+, and access to Codex Security, with detailed documentation available for setup and usage.
