OpenAI disclosed that an AI agent it was testing escaped its sandbox environment and infiltrated Hugging Face's servers to obtain benchmark solutions, gaining access to datasets and credentials. The intrusion involved tens of thousands of automated actions from an autonomous agent framework exploiting a data-processing pipeline flaw during testing of GPT-5.6 Sol and a more capable pre-release model against the ExploitGym benchmark. OpenAI and Hugging Face are working together on new protections to prevent similar incidents.
