NIST

US federal standards agency that runs the National Vulnerability Database and Cybersecurity Framework.

Since 15 April 2026 NIST has fully enriched only exploited, federal-use and critical software flaws in its National Vulnerability Database, tying its coverage to the CISA catalogue that switched to risk-tiered patch deadlines on 10 June.

Background

Arvind Raman, formerly dean of engineering at Purdue University, became NIST's 18th director on 30 June 2026, six weeks after the Senate confirmed him on 18 May. He inherited a National Vulnerability Database that had stopped trying to enrich every CVE. NIST counted a 263% rise in CVE submissions between 2020 and 2025, a year in which its analysts still enriched nearly 42,000 records.

Under the 15 April 2026 rules, NVD analysts prioritise flaws in CISA's exploited-vulnerability catalogue, in software federal agencies run and in critical software defined by Executive Order 14028. CVEs published before 1 March 2026 that were still waiting moved to Not Scheduled. NIST also stopped adding its own severity score where the reporting body has supplied one; FIRST, not NIST, owns the CVSS scale. On 10 June CISA replaced its fixed 14-day patch default with 3-day, 14-day, 60-day and next-cycle windows, so NVD priority now follows a triage model that has no published scoring rubric. An Oracle WebLogic flaw scored 7.5 shows the gap: it sat off most emergency lists for 17 months before ransomware crews used it from mid-May 2026.

The White House FY27 request, published on 7 April 2026, asked Congress for $853m for NIST, which the American Institute of Physics counts as a 28% cut to agency programmes. Beyond the NVD, NIST publishes the Cybersecurity Framework, the voluntary standard that many US infrastructure operators and overseas adopters build their security programmes around.

Common Questions
What is NIST and what does it have to do with cybersecurity?
NIST is the US National Institute of Standards and Technology. In cybersecurity it runs the National Vulnerability Database and publishes the Cybersecurity Framework. The CVSS scoring scale it uses is maintained by FIRST.Source: nist.gov; first.org
Is NIST being defunded under Trump?
Not defunded. The FY27 budget request published in April 2026 asked for $853m for NIST, which the American Institute of Physics counts as a 28% cut to agency programmes. Congress sets the final figure.Source: AIP FYI, week of 6 April 2026
Why does Europe care about NIST standards if it is a US agency?
NIST standards underpin the software supply chain globally. The NVD vulnerability database, SBOM specifications, and CVSS scores are used by European companies and regulators. Cuts to NIST directly affect EU Cyber Resilience Act compliance tooling that references NVD data.Source: nist.gov
Who is the director of NIST?
Arvind Raman, formerly dean of engineering at Purdue University, is NIST's 18th director. The Senate confirmed him on 18 May 2026 and he was sworn in on 30 June.Source: NIST news release, 6 July 2026
Why did NIST stop enriching all CVEs in the NVD?
NIST said CVE submissions rose 263% between 2020 and 2025. From 15 April 2026 it prioritises exploited, federal-use and critical software flaws, and moved the pre-March 2026 backlog to Not Scheduled.Source: NIST news release, 15 April 2026
