Use GitHub innersource advisories to push private dependency fixes inside an enterprise

GitHub innersource advisories are now generally available for enterprise security teams that need private vulnerability distribution inside one company. Use them when an internal package, shared service, or private fork has a flaw that should trigger Dependabot alerts and update pull requests without publishing the advisory to the public GitHub Advisory Database.

The workflow is narrow and useful: create or withdraw advisories through the REST API, keep visibility scoped to the enterprise, and let Dependabot notify repositories that depend on the affected component. It is a fit for internal platforms, monorepos split into reusable packages, and regulated teams that need coordinated remediation before public disclosure.

Treat this as a private remediation lane, not a replacement for public CVEs or external disclosure when customers or open-source users are affected.
