OSV - Open Source Vulnerabilities

osv.dev is a vulnerability database and triage infrastructure for open source projects aimed at helping both open source maintainers and consumers of open source.

This repository contains the infrastructure code that serves osv.dev(and other user tooling). This infrastructure serves as an aggregator of vulnerability databases that have adopted the OpenSSF Vulnerability format.

osv.dev additionally provides infrastructure to ensure affected versions are accurately represented in each vulnerability entry, through bisection and version analysis.

Current data sources

This is an ongoing project. We encourage open source ecosystems to adopt the OpenSSF Vulnerability format to enable open source users to easily aggregate and consume vulnerabilities across all ecosystems. See our blog post for more details.

The following ecosystems have vulnerabilities encoded in this format:

• GitHub Advisory Database (CC-BY 4.0)
• PyPI Advisory Database (CC-BY 4.0)
• Go Vulnerability Database (CC-BY 4.0)
• Rust Advisory Database (CC0 1.0)
• Global Security Database (CC0 1.0)
• OSS-Fuzz (CC-BY 4.0)

Together, these include vulnerabilities from:

• Android
• crates.io
• Debian GNU/Linux
• GitHub Actions
• Go
• Hex
• Linux kernel
• Maven
• npm
• NuGet
• OSS-Fuzz
• Packagist
• Pub
• PyPI
• RubyGems

Data dumps

For convenience, these sources are aggregated and continuously exported to a GCS bucket maintained by OSV: gs://osv-vulnerabilities.

This bucket contains individual entries of the format gs://osv-vulnerabilities/<ECOSYSTEM>/<ID>.json as well as a zip containing all vulnerabilities for each ecosystem at gs://osv-vulnerabilities/<ECOSYSTEM>/all.zip.

E.g. for PyPI vulnerabilities:

# Or download over HTTP via https://osv-vulnerabilities.storage.googleapis.com/PyPI/all.zip
gsutil cp gs://osv-vulnerabilities/PyPI/all.zip .

Viewing the web UI

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

Using the API

  curl -X POST -d \
      '{"commit": "6879efc2c1596d11a6a6ad296f80063b558d5e0f"}' \
      "https://api.osv.dev/v1/query"

  curl -X POST -d \
      '{"version": "2.4.1", "package": {"name": "jinja2", "ecosystem": "PyPI"}}' \
      "https://api.osv.dev/v1/query"

Detailed documentation for using the API can be found at https://osv.dev/docs/.

Using the scanner

Under tools/osv-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.

Usage instructions are located in tools/osv-scanner/README.md.

Architecture

You can find an overview of OSV's architecture here.

This repository

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

• API server (gcp/api)
• Web interface (gcp/appengine)
• Workers for bisection and impact analysis (docker/worker)
• osv-scanner tool, to scan your project and containers for vulnerabilities tracked in OSV

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

git submodule update --init --recursive

Development

See CONTRIBUTING.md.

Third party tools and integrations

There are also community tools that use OSV. Note that these are community built tools and unsupported by the core OSV maintainers.

• G-Rath/osv-detector: A scanner that uses the OSV database.
• Rust client library
• Golang support for the schema
• .NET client library and support for the schema
• EZE-CLI: The one stop shop for security testing in modern development
• OSS Review Toolkit
• Skjold: Security audit python project dependencies against several security advisory databases
• Cortex XSOAR
• Dependency-Track
