Dependabotアラート tell you that your code depends on a package that is insecure.
If your code depends on a package with a security vulnerability, this can cause a range of problems for your project or the people who use it. You should upgrade to a secure version of the package as soon as possible.
For more information about advisory data, see "Browsing security advisories in the GitHub Advisory Database" in the GitHub.com documentation.
Dependabot performs a scan to detect insecure dependencies, and sends Dependabotアラート when:
New advisory data is synchronized to GitHub Enterprise Serverインスタンス each hour from GitHub.com. For more information about advisory data, see "Browsing security advisories in the GitHub Advisory Database" in the GitHub.com documentation.
Note: Only advisories that have been reviewed by GitHub will trigger Dependabotアラート.
The dependency graph for a repository changes. For example, when a contributor pushes a commit to change the packages or versions it depends on. For more information, see "About the dependency graph."
加えて、 GitHub can review any dependencies added, updated, or removed in a pull request made against the default branch of a repository, and flag any changes that would reduce the security of your project. This allows you to spot and deal with vulnerable dependencies before, rather than after, they reach your codebase. 詳しい情報については「Pull Request中の依存関係の変更のレビュー」を参照してください。
For a list of the ecosystems that GitHub Enterprise Server detects insecure dependencies in, see "Supported package ecosystems."
Note: It is important to keep your manifest and lock files up to date. If the dependency graph doesn't accurately reflect your current dependencies and versions, then you could miss alerts for insecure dependencies that you use. You may also get alerts for dependencies that you no longer use.
Enterprise owners must enable Dependabotアラート for GitHub Enterprise Serverインスタンス before you can use this feature. 詳しい情報については「EnterpriseでのDependabotの有効化」を参照してください。
When GitHub Enterprise Server identifies a vulnerable dependency, we generate a Dependabot alert and display it on the Security tab for the repository and in the repository's dependency graph. The alert includes a link to the affected file in the project, and information about a fixed version. GitHub Enterprise Server may also notify the maintainers of affected repositories about the new alert according to their notification preferences. For more information, see "Configuring notifications for Dependabotアラート."
For repositories where Dependabotセキュリティアップデート are enabled, the alert may also contain a link to a pull request to update the manifest or lock file to the minimum version that resolves the vulnerability. For more information, see "About Dependabotセキュリティアップデート."
Note: GitHub Enterprise Server's security features do not claim to catch all vulnerabilities. We actively maintain GitHub Advisory Database and generate alerts with the most up-to-date information. However, we cannot catch everything or tell you about 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 dependency review when necessary.
You can see all of the alerts that affect a particular project in the repository's dependency graph. For more information, see "Viewing and updatng Dependabotアラート."
By default, we notify people with admin permissions in the affected repositories about new Dependabotアラート.
To receive notifications about Dependabotアラート on repositories, you need to watch these repositories, and subscribe to receive "All Activity" notifications or configure custom settings to include "Security alerts." For more information, see "Configuring your watch settings for an individual repository."
You can choose the delivery method for notifications, as well as the frequency at which the notifications are sent to you. For more information, see "Configuring notifications for Dependabotアラート."
You can also see all the Dependabotアラート that correspond to a particular advisory in the GitHub Advisory Database. For more information about advisory data, see "Browsing security advisories in the GitHub Advisory Database" in the GitHub.com documentation.
