About vulnerable dependencies
漏洞是项目代码中的问题，可能被利用来损害机密性、完整性或者该项目或其他使用其代码的项目的可用性。 漏洞的类型、严重性和攻击方法各不相同。
When your code depends on a package that has a security vulnerability, this vulnerable dependency can cause a range of problems for your project or the people who use it.
Detection of vulnerable dependencies
GitHub Enterprise Server detects vulnerable dependencies and sends security alerts when:
- New advisory data is synchronized to GitHub Enterprise Server each hour from GitHub.com. For more information about advisory data, see "Browsing security vulnerabilities in the GitHub Advisory Database."
- 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."
For a list of the ecosystems that GitHub Enterprise Server can detect vulnerabilities and dependencies for, 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 vulnerable dependencies that you use. You may also get alerts for dependencies that you no longer use.
Security alerts for vulnerable dependencies
您的站点管理员必须启用 your GitHub Enterprise Server instance 的漏洞依赖项的安全警报，然后您才可使用此功能。 For more information, see "Enabling alerts for vulnerable dependencies on GitHub Enterprise Server."
When GitHub Enterprise Server identifies a vulnerable dependency, we send a security alert to the maintainers of affected repositories with details of the vulnerability, a link to the affected file in the project, and information about a fixed version.
Note: GitHub Enterprise Server's security features do not claim to catch all vulnerabilities. Though we are always trying to update our vulnerability database and generate alerts with our most up-to-date information, we will not be able to 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 vulnerability review when necessary.
Access to security alerts
You can see all of the alerts that affect 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 Server never publicly discloses identified vulnerabilities for any repository.
您可以选择传送您所关注的仓库中安全警报的方式，以及您接收通知的频率。 For more information, see "Choosing the delivery method for your notifications."
