Devlopers can view the security alerts in the repository's dependency graph, which can be accessed from 'Insights'.
The new service aims to help developers update project dependencies as soon as GitHub becomes aware of a newly announced vulnerability.
GitHub will identify all public repositories that use the affected version of the dependency. Projects under private repositories will need to opt into the vulnerability-detection service.
The alerts should have a big impact on security, given that GitHub now hosts nearly 70 million repositories, with projects that rely on dependent software packages or software libraries that frequently do not get updated when new flaws are disclosed.
Developers can view the security alerts in the repository’s dependency graph, which can be accessed from ‘Insights’.
The alerts are only sent to project owners and others with admin access to repositories. The company promises never to publicly disclose vulnerabilities for a specific repository. Users can choose to receive the alerts by email, web notifications or the GitHub interface.
GitHub’s is also using machine learning to suggest fixes from the GitHub community.
The alerts are based on public vulnerabilities in Ruby gems and NPM, the package manager for Node.js, on MITRE’s Common Vulnerabilities and Exposures (CVE) List. GitHub will add Python to its vulnerability alert service in 2018.
It appears the alerts will be limited to flaws with CVE IDs initially. However, as GitHub notes many publicly disclosed flaws don’t have CVE IDs. It suggests future improvements will help it identify more vulnerabilities as it collects more data about them.
