Why the NVD update matters
NIST just admitted the National Vulnerability Database is hitting a wall – the sheer volume of new flaws is outstripping its ability to process them.
Scaling challenges exposed
In an April 2026 statement, the agency outlined concrete changes to its operations, acknowledging that the backlog was becoming a liability for anyone relying on NVD data for patch prioritisation.
What “Not Scheduled” really means
Roughly 30,000 vulnerabilities published before 1 March 2026 were re‑tagged as “Not Scheduled”. Those entries no longer carry a projected release date for a CVSS score or remediation guidance, effectively putting them in a limbo that security teams must navigate on their own.
Action1’s take on multi‑source vulnerability management
The sponsored piece from Action1 argues the only realistic path forward is to pull intelligence from everywhere, not just the NVD.
How the approach works
Action1 aggregates feeds from NVD, CISA’s KEV catalog, Microsoft’s MSRC, vendor release notes and other public sources, then runs an automated scoring engine that spits out a priority rating within minutes.
Practical steps for security teams
- Don’t rely solely on NVD – supplement with CISA KEV, vendor advisories and Microsoft security updates.
- Deploy an automated enrichment pipeline that normalises data and assigns risk scores in near‑real time.
- Track “Not Scheduled” entries manually or via a script that flags them for deeper analysis.
- Validate any AI‑driven findings against multiple trusted feeds before acting.
- Allocate resources to maintain an internal knowledge base that can fill gaps when public sources lag.
