OpenAI just open-sourced Codex Security

OpenAI has open-sourced Codex Security, a CLI and TypeScript SDK tool designed to find, validate, and fix security vulnerabilities in code. The tool allows developers to scan repositories, review changes, track findings over time, and integrate security checks into CI/CD pipelines. It requires Node.js 22 or later and Python 3.10 or later, with access available through OpenAI's API.
