Introduction to OSV

OpenSSF Scorecard

OSV enables developers to identify known third-party open source dependency vulnerabilities that pose genuine risk to their application and its environment, so they can focus remediation efforts on the vulnerabilities that matter and sustainably manage vulnerabilities that do not affect them.

This repository contains the infrastructure code that serves (including the API). This infrastructure serves as an aggregator of vulnerability databases that have adopted the OpenSSF Vulnerability format. additionally provides infrastructure to ensure affected versions are accurately represented in each vulnerability entry, through bisection and version analysis.

Further information on the infrastructure architecture is available here.

OSV-Scanner is the first-party tool that leverages’s data, using its API.

This is a diagram that shows the relationship between the vulnerability databases that use the OSV format and how all those entries are collated at Open source users can query for known vulnerabilities by version number or commit hash.
