About security alerts for vulnerable dependencies

GitHub Enterprise sends security alerts when we detect vulnerabilities affecting your repository.

About security vulnerabilities

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. 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 Enterprise 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 a security alert. For more information about the GitHub Advisory Database, see "Browsing security vulnerabilities in the GitHub Advisory Database."

Security alerts for vulnerable dependencies

When a new vulnerability is added to the GitHub Advisory Database, we identify repositories that use the affected version of the dependency and send a security alert to repository maintainers.

Each security alert includes a severity level and a link to the affected file in your project. When available, the alert will include further details about the vulnerability.

You can see all of the alerts affecting a particular project in the repository's dependency graph.

We send security alerts to people with admin permissions in the affected repositories by default. GitHub Enterprise never publicly discloses identified vulnerabilities for any repository.

Your site administrator must enable security alerts for vulnerable dependencies for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Enabling security alerts for vulnerable dependencies on GitHub Enterprise Server."

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

Note: GitHub Enterprise's security features, such as security alerts, 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 security alerts

By default, you will receive a weekly email summarizing security alerts for up to 10 of your repositories. You also can choose to receive security alerts individually by email, in a daily digest email, in your web notifications, or in the GitHub Enterprise user interface. For more information, see "Choosing the delivery method for your notifications."
