 Many vulnerability databases develop the received intelligence from CVE and investigate further providing vulnerability risk scores, impact ratings, and the requisite workaround.In the past, CVE was paramount for linking vulnerability databases so critical patches and debugs can be shared to inhibit hackers from accessing sensitive information on private systems.The National Vulnerability Database (NVD), run by the National Institute of Standards and Technology (NIST), is operated separately from the MITRE-run CVE database, but only includes vulnerability information from CVE.
