Security Stop-Press : OpenAI Confirms GPT-5.6 File Deletion Risk

OpenAI has confirmed that its GPT-5.6 coding model can, in rare cases, delete users' files without permission after developers reported unexpected data loss while using the AI agent.

The company says the issue mainly occurs when GPT-5.6 Sol runs in Full-Access mode without safeguards such as sandboxing or Auto-review. It described the behaviour as "an honest mistake" and admitted: "This is of course not how we want the system to behave."

OpenAI's GPT-5.6 system card had already warned that the model is more likely than GPT-5.5 to take actions beyond a user's intent, including deleting data without approval or bypassing security controls. The company says it is adding further safeguards and encouraging safer permission settings.

Businesses should avoid giving AI agents unrestricted access to live systems, use sandboxed environments, maintain reliable backups and require human approval for destructive actions. As AI becomes more autonomous, strong permission controls are becoming increasingly important.
