Reading that article closely it says nothing about an NVD budget cut, only a NIST one. They were trackijg the changes after NIST's budget was cut, not NVD's. As pointed out below, CISA announced a cut and then NIST more than made up for it by reallocating funds, for an NVD funding increase, even though NIST had their overall budget cut.
One of your references has budget numbers that are two orders (?!) of magnitude higher than the CISA number. Hopefully someone can chime in with granular historical data for NIST NVD and MITRE-via-NIST CVE funding.
