The GitHub Advisory Database is the largest database of vulnerabilities in software dependencies in the world. It is maintained by a dedicated team of full-time curators and powers the security audit experience for npm and NuGet, as well as GitHub’s own Dependabot alerts. By making it easier to contribute to and consume, we hope it will power even more experiences and will further help improve the security of all software.
