Back when I first heard of it, the HuggingFace hack reminded me about how you don't have to be particularly smart to find vulns, just aggressive in looking for them. AFL on its own "learned" how to construct well-formed JPEGs and PDFs by fuzzing decoders for these formats, back in the pre-LLM dark ages.
Of course the HuggingFace hack proved to be much more than that...
