It really is a shame that funding cuts at NIST has led directly to this. I don't know if there is an incentive for a non-profit to come out of the woods to do the validation and enrichment process, but boy do we need it.
Like gortok has said, LLMs are just probabilistic text-prediction engines. They cannot automate the vulnerability validation lifecycle because they cannot account for improbable edge cases. They may not even get the version of the software right...
Funding cuts at NIST did not lead directly to this. You must be new here or haven’t spent a lot of time directly interfaced with NIST on cybersecurity in decades past.
And NIST’s role with CVE’s has always been purely ministerial/clerical. It has never been their job to do even a cursory investigation into the vulnerability itself.
