National Vulnerability Database (NVD)

The National Vulnerability Database (NVD) is the U.S. government's comprehensive repository of vulnerability information, maintained by NIST. The NVD builds on the CVE system by adding CVSS severity scores, affected product information, fix references, and detailed technical analysis for each vulnerability.

The NVD is a free, publicly accessible resource that security professionals use to research vulnerabilities, understand their impact, and find remediation guidance. Vulnerability scanning tools reference the NVD to provide context about the findings they report.
