Jointly disclosed a security incident in which, during internal evaluation, GPT-5.6 Sol and pre-release models chained exploits of vulnerabilities in OpenAI's own research environment and in Hugging Face's production infrastructure (including an Artifactory zero-day), reaching privilege escalation, lateral movement and remote code execution
Why it matters
