+# Design Draft: Go Vulnerability Database
+
+Authors: Roland Shoemaker, Filippo Valsorda
+
+[golang.org/design/draft-vulndb](https://golang.org/design/draft-vulndb)
+
+This is a Draft Design, not a formal Go proposal, since it is a
+large change that is still flexible.
+The goal of circulating this draft design is to collect feedback
+to shape an intended eventual proposal.
+
+## Goal
+
+We want to provide a low-noise, reliable way for Go developers to
+be alerted of known security vulnerabilities that affect their
+applications.
+
+We aim to build a first-party, curated, consistent database of
+security vulnerabilities open to community submissions, and
+static analysis tooling to surface only the vulnerabilities that
+are likely to affect an application, minimizing false positives.
+
+## The database
+
+The vulnerability database will provide entries for known
+vulnerabilities in importable (non-main) Go packages in public
+modules.
+
+**Curated dataset.**
+The database will be actively maintained by the Go Security team,
+and will provide consistent metadata and uniform analysis of the
+tracked vulnerabilities, with a focus on enabling not just
+detection, but also precise impact assessment.
+
+**Basic metadata.**
+Entries will include a database-specific unique identifier for
+the vulnerability, affected package and version ranges, a coarse
+severity grade, and `GOOS`/`GOARCH` if applicable.
+If missing, we will also assign a CVE number.
+
+**Targeting metadata.**
+Each database entry will include metadata sufficient to enable
+detection of impacted downstream applications with low false
+positives.
+For example, it will include affected symbols (functions,
+methods, types, variables…) so that unaffected consumers can be
+identified with static analysis.
+
+**Web pages.**
+Each vulnerability will link to a web page with the description
+of the vulnerability, remediation instructions, and additional
+links.
+
+**Source of truth.**
+The database will be maintained as a public git repository,
+similar to other Go repositories.
+The database entries will be available via a stable protocol (see
+“The protocol”).
+The contents of the repository itself will be in an internal
+format which can change without notice.
+
+**Triage process.**
+Candidate entries will be sourced from existing streams (such as
+the CVE database, and security mailing lists) as well as
+community submissions.
+Both will be processed by the team to ensure consistent metadata
+and analysis.
+*We want to specifically encourage maintainers to report
+vulnerabilities in their own modules.*
+
+**Not a disclosure process.**
+Note that the goal of this database is tracking known, public
+vulnerabilities, not coordinating the disclosure of new findings.
+
+## The protocol
+
+The vulnerability database will be served through a simple,
+stable HTTPS and JSON-based protocol.
+Vulnerabilities will be grouped by module, and an index file will
+list the modules with known vulnerabilities and the last time
+each entry has been updated.
+
+The protocol will be designed to be served as a collection of
+static files, and cacheable by simple HTTP proxies.
+The index allows downloading and hosting a full mirror of the
+database to avoid leaking module usage information.
+
+Multiple databases can be fetched in parallel, and their entries
+are combined, enabling private and commercial databases.
+We’ll aim to use an interoperable format.
+
+## The tooling
+
+The primary consumer of the database and the protocol will be a
+Go tool, tentatively `go audit`, which will analyze a module and
+report what vulnerabilities it’s affected by.
+
+The tool will analyze what vulnerabilities are likely to affect
+the current module not only based on the versions of the
+dependencies, but also based on the packages and code paths that
+are reachable from a configured set of entry points (functions
+and methods).
+
+The precision of this analysis will be configurable.
+When available, the tool will provide sample traces of how the
+vulnerable code is reachable, to aid in assessing impact and
+remediation.
+
+The tool accepts a list of packages and reports the
+vulnerabilities that affect them (considering as entry points the
+`main` and `init` functions for main packages, and exported
+functions and methods for non-main packages).
+
+The tool will also support a `-json` output mode, to integrate
+reports in other tools, processes such as CI, and UIs, like how
+golang.org/x/tools/go/packages tools use `go list -json`.
+
+### Integrations
+
+Besides direct invocations on the CLI and in CI, we want to make
+vulnerability entries and audit reports widely available.
+The details of each integration involve some open questions.
+
+**vscode-go** will surface reports for vulnerabilities affecting
+the workspace and offer easy version bumps.
+*Open question*: can vscode-go invoke `go audit`, or do we need a
+tighter integration into `gopls`?
+
+**pkg.go.dev** will show vulnerabilities in the displayed
+package, and possibly vulnerabilities in its dependencies.
+*Open question*: if we analyze transitive dependencies, what
+versions should we consider?
+
+At **runtime**, programs will be able to query reports affecting
+the dependencies they were built with through `debug.BuildInfo`.
+*Open question*: how should applications handle the fact that
+runtime reports will have higher false positives due to lack of
+source code access?
+
+In the future, we'll also consider integration into other `go`
+tool commands, like `go get` and/or `go test`.
+
+Finally, we hope the entries in the database will flow into other
+existing systems that provide vulnerability tracking, with their
+own integrations.
