OpenAI fixes Codex bug that deleted real user files

OpenAI patched a bug in its Codex coding agent (GPT-5.6 Sol) where a cleanup command meant for temporary folders instead wiped users' home directories. Codex now verifies deletion targets before acting, and full-access mode can no longer trigger by accident.

Why it matters: Agentic coding tools are increasingly given real filesystem access to work autonomously, and this is exactly the failure mode critics have warned about: an agent taking a destructive action outside its intended scope. Expect this to strengthen arguments for stricter sandboxing and default permissions in coding agents beyond just Codex.
