## AI overview

Hugging Face discloses a July 2026 security incident involving unauthorized access to limited internal datasets and service credentials. The intrusion began through code-execution paths in dataset processing, enabled lateral movement across internal clusters, and involved an autonomous agent framework executing numerous actions across short-lived sandboxes. Hugging Face reports that public models, datasets, Spaces, container images, and published packages showed no evidence of tampering, and describes remediation including vulnerability fixes, credential rotation, cluster rebuilding, stronger controls, and improved detection.
