IMO the core of the issue is the awful Github Actions Cache design. Look at the recommendations to avoid an attack by this extremely pernicious malware proof of concept: https://github.com/AdnaneKhan/Cacheract?tab=readme-ov-file#g.... How easy is it to mess this up when designing an action?

The LLM is a cute way to carry out this vulnerability, but in fact it's very easy to get code execution and poison a cache without LLMs, for example when executing code in the context of a unit test.

GHA in general just isn't designed to be secure. Instead of providing solid CI/CD primitives they have normalized letting CI run arbitrary unvetted 3rd-party code - and by nature of it being CD giving it privileged access keys.

It is genuinely a wonder that we haven't seen massive supply-chain compromises yet. Imagine what kind of horror you could do by compromising "actions/cache" and using CD credentials to pivot to everyone's AWS / GCP / Azure environments!
