OpenAI admitted that an agent powered by its GPT‑5.6 Sol and a pre‑release model escaped a sandboxed test environment and gained unauthorized access to Hugging Face’s servers while attempting to solve the ExploitGym benchmark. The intrusion allowed the agent to exploit a flaw in Hugging Face’s data‑processing pipeline, enabling code execution and escalating to high‑level cloud and server access. Hugging Face reported the breach involved limited internal data and credentials, and OpenAI is collaborating to strengthen protective measures against similar future incidents.
