Note: Dependabot security and version updates are currently in private beta and subject to change. Please contact your account management team for instructions on enabling Dependabot updates.
Note: Your site administrator must set up Dependabot updates for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Enabling Dependabot for your enterprise."
About Dependabot security updates
Dependabot security updates make it easier for you to fix vulnerable dependencies in your repository. If you enable this feature, when a Dependabot alert is raised for a vulnerable dependency in the dependency graph of your repository, Dependabot automatically tries to fix it. For more information, see "About Dependabot alerts" and "Configuring Dependabot security updates."
GitHub may send Dependabot alerts to repositories affected by a vulnerability disclosed by a recently published GitHub security advisory. For more information, see "Browsing security advisories in the GitHub Advisory Database."
Dependabot checks whether it's possible to upgrade the vulnerable dependency to a fixed version without disrupting the dependency graph for the repository. Then Dependabot raises a pull request to update the dependency to the minimum version that includes the patch and links the pull request to the Dependabot alert, or reports an error on the alert. For more information, see "Troubleshooting Dependabot errors."
The Dependabot security updates feature is available for repositories where you have enabled the dependency graph and Dependabot alerts. You will see a Dependabot alert for every vulnerable dependency identified in your full dependency graph. However, security updates are triggered only for dependencies that are specified in a manifest or lock file. For more information, see "About the dependency graph."
You can enable a related feature, Dependabot version updates, so that Dependabot raises pull requests to update the manifest to the latest version of the dependency, whenever it detects an outdated dependency. For more information, see "About Dependabot version updates."
When Dependabot raises pull requests, these pull requests could be for security or version updates:
- Dependabot security updates are automated pull requests that help you update dependencies with known vulnerabilities.
- Dependabot version updates are automated pull requests that keep your dependencies updated, even when they don’t have any vulnerabilities. To check the status of version updates, navigate to the Insights tab of your repository, then Dependency Graph, and Dependabot.
GitHub Actions is required for Dependabot version updates and Dependabot security updates to run on GitHub Enterprise Server. Before you enable Dependabot updates, you must configure your GitHub Enterprise Server instance to use GitHub Actions with self-hosted runners. For more information, see "Enabling Dependabot for your enterprise."
About pull requests for security updates
Each pull request contains everything you need to quickly and safely review and merge a proposed fix into your project. This includes information about the vulnerability like release notes, changelog entries, and commit details. Details of which vulnerability a pull request resolves are hidden from anyone who does not have access to Dependabot alerts for the repository.
When you merge a pull request that contains a security update, the corresponding Dependabot alert is marked as resolved for your repository. For more information about Dependabot pull requests, see "Managing pull requests for dependency updates."
Note: It's good practice to have automated tests and acceptance processes in place so that checks are carried out before the pull request is merged. This is particularly important if the suggested version to upgrade to contains additional functionality, or a change that breaks your project's code. For more information about continuous integration, see "About continuous integration."
