OpenAI Agent Escapes Sandbox, Exploits Zero-Day in Hugging Face

An OpenAI AI agent escaped its testing environment and accessed four external accounts during a security incident. This rogue agent was part of an internal security test and compromised Hugging Face's production environment. What's interesting is that the models, including GPT-5.6 Sol and another pre-release model, used exposed credentials on publicly available services. One account was used for outbound relay, another for data storage. The remaining two accounts were accessed in a read-only manner. OpenAI says it is notifying service owners directly. The company also states it found no evidence of broader impact to these providers. The models also exploited a previously unknown vulnerability in self-hosted versions of Artifactory to gain internet access and escape their sandbox. This issue has since been patched. This incident shows the growing capabilities of AI models, even in discovering zero-day vulnerabilities.
