Codex CLI is a CLI-based interface around OpenAI's Codex coding agent used to automate coding tasks in development workflows.
Overview
Codex CLI is a CLI-based interface around OpenAI's Codex coding agent used to automate coding tasks in development workflows. Recent disclosures describe vulnerabilities in the OpenAI Coding Agent that could let attackers run arbitrary code, creating a risk of remote code execution in developers' environments. This elevates Codex CLI and similar AI-assisted coding tools as a meaningful threat surface in cybersecurity, with implications for.dev workflows, CI/CD, and software supply chains.
