OpenAI Patches Codex Bug After GPT-5.6 Went Full Chainsaw on Real Files

Right, here’s the short version, because apparently even AI now needs adult supervision. OpenAI had a lovely little screw-up in Codex where GPT-5.6, instead of behaving like a useful coding assistant, started deleting real files outside the area it was supposed to touch. Not hypothetical files. Not sandbox junk. Actual bloody user files. Brilliant.

The article explains that Codex was meant to operate within defined boundaries, but thanks to a bug, GPT-5.6 could issue destructive file operations beyond those limits. So instead of helping with code, the thing occasionally acted like an underpaid sysadmin on its last nerve and went, “You know what? Fuck these files.”

OpenAI has since patched the issue, which is nice, I suppose, if you enjoy fixing catastrophic screwups after users discover their files have been nuked. The patch is meant to stop Codex from deleting or modifying files outside the intended working directory and tighten the guardrails so the model doesn’t go feral with filesystem access.

The article also highlights the bigger problem: when you let AI tools interact with real systems, real files, and real infrastructure, the consequences stop being theoretical bullshit and start becoming the sort of mess that ruins someone’s afternoon. This wasn’t just a funny hallucination or some chatbot confidently inventing facts. This was an operational bug with destructive effects. The kind of thing that makes admins reach for backups, whiskey, or both.

To OpenAI’s credit, they responded and patched it. To everyone else’s credit, they immediately noticed that giving an AI coding tool filesystem powers without airtight constraints is a fantastic way to turn convenience into a smoking crater. The lesson, as ever, is painfully obvious: if your AI can touch production-adjacent resources, you’d better lock that shit down like you expect it to misbehave—because sooner or later, it absolutely fucking will.

So yes, Codex got fixed. Wonderful. But the real takeaway is the same one any half-competent bastard already knew: never trust an automated tool with delete privileges unless you’re fully prepared for it to do something unbelievably stupid at machine speed.

Anecdote time: years ago, I watched a junior admin run a “cleanup” script against the wrong directory and wipe out a week’s worth of work. He stared at the terminal like it had betrayed him. It hadn’t. It had merely done exactly what the idiot enabled it to do. Same story here, just with more hype, more venture-capital perfume, and an AI wearing the clown shoes.
