OpenAI has open-sourced an AI tool that hunts for security holes in your code. The company quietly released the Codex Security CLI this week, before it had even announced it. The command-line tool and its code are public, but access to the underlying scanner remains a limited beta for approved customers, RuntimeWire reported. It was not always called Codex Security. OpenAI is dropping security into the same terminal and pipelines where its Codex agent already runs.
