About alerts for vulnerable dependencies

GitHub sends GitHub Dependabotアラート when we detect vulnerabilities affecting your repository.

About security vulnerabilities in dependencies

脆弱性とは、プロジェクトあるいはそのコードを利用する他のプロジェクトにおいて、秘密性、一貫性、可用性を損なうために悪用されうる、プロジェクトコードの問題です。 Depending on the severity level and the way your project uses the dependency, vulnerabilities can cause a range of problems for your project or the people who use it. You can track and resolve vulnerabilities for certain types of dependencies in your GitHub repository.

If GitHub detects a vulnerability from the GitHub Advisory Database or WhiteSource in one of the dependencies in your repository's dependency graph, we'll send you an alert. For more information about the GitHub Advisory Database, see "Browsing security vulnerabilities in the GitHub Advisory Database."

GitHub Dependabot alerts and security updates for vulnerable dependencies

When a new vulnerability is added to the GitHub Advisory Database, we identify public repositories (and private repositories that have opted in to vulnerability detection) that use the affected version of the dependency, send a GitHub Dependabot alert to repository maintainers, and generate a GitHub Dependabot security update.

Each Dependabot alert includes a severity level, a link to the affected file in your project, and a link to a pull request containing a security update that resolves the vulnerability. When available, the alert will include further details about the vulnerability.

You can see all of the alerts affecting a particular project on the repository's Security tab or in the repository's dependency graph. For more information, see "Viewing and updating vulnerable dependencies in your repository."

We send Dependabot alerts to people with admin permissions in the affected repositories by default. GitHub never publicly discloses identified vulnerabilities for any repository. You can also enable Dependabot alerts for additional people or teams working in organization-owned repositories. For more information, see "Managing alerts for vulnerable dependencies in your organization's repositories."

GitHub Dependabotセキュリティアップデート update vulnerable dependencies to the minimum version that resolves the vulnerability. Security updates are automatically enabled in repositories that use the dependency graph and GitHub Dependabotアラート, but you can choose to disable automatic pull requests and generate security updates manually instead. For more information, see "Configuring GitHub Dependabotセキュリティアップデート."

GitHub detects and alerts on vulnerable dependencies in public repositories by default. To receive GitHub Dependabotアラート for vulnerable dependencies in a private repository, an owner of or person with admin access to the repository must enable the dependency graph and GitHub Dependabotアラート in the repository. For more information, see "Managing data use settings for your private repository."

For a list of the supported languages that GitHub can detect vulnerabilities and dependencies for, see "Listing the packages that a repository depends on."

Note: GitHub's security features do not claim to catch all vulnerabilities. Though we are always trying to update our vulnerability database and alert you with our most up-to-date information, we will not be able to catch everything or alert you to known vulnerabilities within a guaranteed time frame. These features are not substitutes for human review of each dependency for potential vulnerabilities or any other issues, and we recommend consulting with a security service or conducting a thorough vulnerability review when necessary.

Configuring notifications for GitHub Dependabotアラート

By default, you will receive GitHub Dependabotアラート by email, grouped by the specific vulnerability. You can also choose to receive GitHub Dependabotアラート in a weekly email summarizing alerts for up to 10 of your repositories, in your web notifications, or in the GitHub user interface. For more information, see Configuring notifications ."

1つ以上のリポジトリに影響するセキュリティアラートに関するメール通知には、X-GitHub-Severityヘッダフィールドが含まれます。 X-GitHub-Severityヘッダフィールドの値を使って、セキュリティアラートのメール通知をフィルタリングできます。 For more information, see "Configuring notifications."
