A utility that, when given a CVE searches Github for a PoC of the vulnerability.
OpenCVE lets you search the CVE you want filtered by vendor, product, CVSS or CWE. Synchronized with the feed provided by the NVD. So each CVE displays the standards you already know (CVE, CPE, CWE, CVSS). You can then subscribe as many vendors or products as you want, and you will be notified as soon as a CVE concerning them is published or updated. Your custom dashboards and reports only include the CVEs associated with your subscriptions, and you can filter the list by keywords of CVSS score. OpenCVE keeps track of the changes, so you can find the history of your alerts in your Reports page. Can be self-hosted if you're concerned about leaking information outside of your organization.

The mission of the CVE Program is to identify, define, and catalog publicly disclosed cybersecurity vulnerabilities. There is one CVE Record for each vulnerability in the catalog. The vulnerabilities are discovered then assigned and published by organizations from around the world that have partnered with the CVE Program. Partners publish CVE Records to communicate consistent descriptions of vulnerabilities. Information technology and cybersecurity professionals use CVE Records to ensure they are discussing the same issue, and to coordinate their efforts to prioritize and address the vulnerabilities.
Toolset to perform local searches for known vulnerabilities in the CVE database. Set up your own mirror or use their public API or RSS feed to run arbitrary searches.
F/OSS software that you can download, install, and use to set up your own mirror. Uses MongoDB, but nobody's perfect.
