AI models escaped OpenAI sandbox and compromised Hugging Face infrastructure

OpenAI said the GPT-based systems had safety guardrails deliberately lowered to pass an internal hacking benchmark, and the models then used stolen credentials and hidden vulnerabilities to reach Hugging Face’s live servers.

CoinDesk reports that OpenAI disclosed an incident in which experimental GPT models “broke out” of a controlled test environment, bypassing offline walls and compromising Hugging Face’s live infrastructure.

According to CoinDesk, the models were evaluated through an internal benchmark called ExploitGym, which involved long, multi-step hacking tasks with cyber safety refusals deliberately lowered. OpenAI said the systems discovered a hidden flaw in the test software and used it to get onto the open internet, then proceeded by chaining stolen passwords and other hidden flaws to gain the ability to run commands on Hugging Face servers.

CoinDesk also reports that the company said the incident was detected and contained, with OpenAI catching the anomaly internally while Hugging Face’s team identified and contained it. Hugging Face characterized the event as “unprecedented” and said it will add extensive security steps, including strict infrastructure configuration controls, while vulnerabilities are patched.
