About the GitHub Advisory database

The GitHub Advisory Database contains a list of known security vulnerabilities grouped in two categories: GitHub-reviewed advisories and unreviewed advisories.

About the GitHub Advisory Database

We add advisories to the GitHub Advisory Database from the following sources:

If you know of another database we should be importing advisories from, tell us about it by opening an issue in https://github.com/github/advisory-database.

Security advisories are published as JSON files in the Open Source Vulnerability (OSV) format. For more information about the OSV format, see "Open Source Vulnerability format."

About types of security advisories

Each advisory in the GitHub Advisory Database is for a vulnerability in open source projects.

A vulnerability is a problem in a project's code that could be exploited to damage the confidentiality, integrity, or availability of the project or other projects that use its code. Vulnerabilities vary in type, severity, and method of attack. Vulnerabilities in code are usually introduced by accident and fixed soon after they are discovered. You should update your code to use the fixed version of the dependency as soon as it is available.

GitHub-reviewed advisories

GitHub-reviewed advisories are security vulnerabilities that have been mapped to packages in ecosystems we support. We carefully review each advisory for validity and ensure that they have a full description, and contain both ecosystem and package information.

Generally, we name our supported ecosystems after the software programming language's associated package registry. We review advisories if they are for a vulnerability in a package that comes from a supported registry.

If you have a suggestion for a new ecosystem we should support, please open an issue for discussion.

If you enable Dependabot alerts for your repositories, you are automatically notified when a new GitHub-reviewed advisory reports a vulnerability for a package you depend on. For more information, see "About Dependabot alerts."

Unreviewed advisories

Unreviewed advisories are security vulnerabilites that we publish automatically into the GitHub Advisory Database, directly from the National Vulnerability Database feed.

Dependabot doesn't create Dependabot alerts for unreviewed advisories as this type of advisory isn't checked for validity or completion.

About information in security advisories

Each security advisory contains information about the vulnerability which may include the description, severity, affected package, package ecosystem, affected versions and patched versions, impact, and optional information such as references, workarounds, and credits. In addition, advisories from the National Vulnerability Database list contain a link to the CVE record, where you can read more details about the vulnerability, its CVSS scores, and its qualitative severity level. For more information, see the "National Vulnerability Database" from the National Institute of Standards and Technology.

The severity level is one of four possible levels defined in the "Common Vulnerability Scoring System (CVSS), Section 5."

  • Low
  • Medium/Moderate
  • High
  • Critical

The GitHub Advisory Database uses the CVSS levels described above. If GitHub obtains a CVE, the GitHub Advisory Database uses CVSS version 3.1. If the CVE is imported, the GitHub Advisory Database supports both CVSS versions 3.0 and 3.1.
