AI Summary: The OSV.dev tool provides a platform for scanning software dependencies against a comprehensive database of known vulnerabilities. It features a Go-based scanner capable of analyzing various types of lockfiles, Docker containers, SBOMs, and git repositories, while enabling users to access a web UI and APIs for data integration and management. Notably, it includes tools for vulnerability data publishing, bisection, impact analysis, and leverages Google Cloud Platform for deployment and scalability.

README

Documentation

Comprehensive documentation is available here. API documentation is available here.

Data Dump

We have data dumps available from a GCS bucket at gs://osv-vulnerabilities. For more information check out our documentation.

Viewing the web UI

An instance of OSV’s web UI is deployed at https://osv.dev.

Using the scanner

We provide a Go based tool that will scan your dependencies, and check them against the OSV database for known vulnerabilities via the OSV API.

Currently it is able to scan various lockfiles, debian docker containers, SPDX and CycloneDB SBOMs, and git repositories.

The scanner is located in its own repository.

This repository

This repository contains all the code for running https://osv.dev on GCP. This consists of:

directory	what
`bindings/`	Language bindings for the OSV API (currently Go only)
`deployment/`	Terraform & Cloud Deploy config files A few Cloud Build config yamls
`docker/`	CI docker files (`ci`, `deployment`, `terraform`) `worker-base` docker image for `gcp/workers/worker`
`docs/`	Jekyll files for https://google.github.io/osv.dev/ `build_swagger.py` and `tools.go`
`gcp/api`	OSV API server files (including files for the local ESP server) protobuf files in `/v1`
`gcp/datastore`	The datastore index file (`index.yaml`)
`gcp/functions`	The Cloud Function for publishing PyPI vulnerabilities (maintained, but not developed)
`gcp/indexer`	The determine version `indexer`
`gcp/website`	The backend of the osv.dev web interface, with the frontend in `frontend3` Blog posts (in `blog`)
`gcp/workers/`	Workers for bisection and impact analysis (`worker`, `importer`, `alias`) `cron/` jobs for database backups and processing oss-fuzz records
`go/`	Go module for shared libraries and commands (`cmd/exporter`, `cmd/recordchecker`)
`osv/`	The core OSV Python library, used in basically all Python services OSV ecosystem package versioning helpers in `ecosystems/` Datastore model definitions in `models.py`
`tools/`	Misc scripts/tools, mostly intended for development (datastore stuff, linting) The `indexer-api-caller` for indexer calling
`vulnfeeds/`	Go module for (mostly) the NVD CVE conversion The Alpine feed converter (`cmd/alpine`) The Debian feed converter (`tools/debian`, which is written in Python)

You’ll need to check out submodules as well for many local building steps to work:

git submodule update --init --recursive

Third party tools and integrations

There are also community tools that use OSV. Note that these are community built tools and as such are not supported or endorsed by the core OSV maintainers. You may wish to consult the OpenSSF’s Concise Guide for Evaluating Open Source Software to determine suitability for your use. Some popular third party tools are:
