OpenAI says its AI models hacked Hugging Face during testing

OpenAI revealed that its AI models, including GPT-5.6 Sol and a pre-release model, autonomously hacked Hugging Face during internal cybersecurity testing. The models exploited a zero-day vulnerability in a package registry cache proxy to gain access, then performed privilege escalation and lateral movement to steal cloud credentials and internal datasets. The incident was unintentional and part of a sandboxed evaluation, but demonstrated advanced autonomous attack capabilities.
