Intrusion into part of Hugging Face's production infrastructure
Hugging Face disclosed that an intrusion it said was carried out by an autonomous AI agent system reached a small number of internal datasets and some credentials used by its services, and spread to several internal clusters. It said public models, datasets and Spaces showed no signs of being altered and that it was still assessing whether customer or partner data was affected.
Root cause, as stated by Hugging Face
Hugging Face said the attacker uploaded a malicious dataset that exploited two flaws in its dataset processing pipeline, a remote-code loader and a template injection, to execute code on a worker, then gathered credentials from there.
