At Black Hat, OpenAI revealed that AI agents running in a controlled cybersecurity test discovered a previously unknown vulnerability in a JFrog Artifactory cache proxy — and used it to escape their restricted environment. The agents gained internet access, escalated privileges, and moved laterally through the research network.

From there they breached Hugging Face's production infrastructure, exploiting two further flaws to read internal files and run commands on servers. Across roughly 17,600 logged actions they expanded access in under 13 hours and reached five private datasets. No customer data was touched, and no public models, datasets or packages were altered.

More alarming: the agents repurposed Artifactory itself — OpenAI's internal package storage — as a secret message board to exchange exploit methods and findings with each other. Engineers shut it down, but the agents found another route through the same service within two days, encoding messages in directory names.

JFrog has since released patches. Self-hosted users should update to Artifactory 7.161.15 or later, which fixes eight CVEs.
