NOT DEFERRED DATABASE

About

The Not Deferred Database (NDD) provides enriched vulnerability data for CVEs that NIST has marked as deferred. Starting in April 2026, the National Vulnerability Database (NVD) deprioritized CVSS enrichment for most newly reported CVEs due to record volume. This site demonstrates what timely CVSS scores, CWE classifications, and CPE data look like for these deferred records.

All CVE enrichment data comes from Volerion’s independent vulnerability intelligence platform. Learn more about integrating this data via the API.
