Supported lockfiles

A wide range of lockfiles are supported by utilizing this lockfile package.

Language Compatible Lockfile(s)
C/C++ conan.lock
C/C++ commit scanning
Dart pubspec.lock
Elixir mix.lock
Go go.mod
Java buildscript-gradle.lockfile
Javascript package-lock.json
PHP composer.lock
Python Pipfile.lock
R renv.lock
Ruby Gemfile.lock
Rust Cargo.lock

Alpine Package Keeper and Debian Package Keeper

The scanner also supports:

  • installed files used by the Alpine Package Keeper (apk) that typically live at /lib/apk/db/installed
  • status files used by the Debian Package manager (dpkg) that typically live at /var/lib/dpkg/status

however you must specify them explicitly using the --lockfile flag:

osv-scanner --lockfile 'apk-installed:/lib/apk/db/installed'
osv-scanner --lockfile 'dpkg-status:/var/lib/dpkg/status'

C/C++ scanning

With the addition of vulnerable commit ranges to the database, OSV-Scanner now supports vendored and submoduled C/C++ dependencies

Because the C/C++ ecosystem does not have a centralized package manager, C/C++ dependencies tend to be bundled with the project. Dependencies are either submoduled or vendored. In either case, OSV-Scanner is able to find known vulnerabilities in your project dependencies.

OSV-Scanner’s C/C++ support is based on commit-level data. OSV’s commit-level data covers the majority of C/C++ vulnerabilities within the OSV database, but users should be aware that there may be vulnerabilities in their dependencies that could be excluded from OSV-Scanner results. Adding more commit-level data to the database is an ongoing project.

Submoduled dependencies

Submoduled dependencies are included in the project folder retain their Git histories. To scan a C/C++ project with submoduled dependencies:

  1. Navigate to the root folder of your project.
  2. Ensure that your submodules are up to date using git submodule update.
  3. Run scanner using osv-scanner -r ..

Vendored dependencies

Vendored dependencies have been directly copied into the project folder, but do not retain their Git histories. OSV-Scanner uses OSV’s determineversion API to estimate each dependency’s version (and associated Git Commit). Vulnerabilities for the estimated version are returned. This process requires no additional work from the user. Run OSV-Scanner as you normally would.

Custom Lockfiles

If you have a custom lockfile that we do not support or prefer to do your own custom parsing, you can extract the custom lockfile information and create a custom intermediate file containing dependency information so that osv-scanner can still check for vulnerabilities.

Once you extracted your own dependency information, place it in a osv-scanner.json file, with the same format as the JSON output of osv-scanner, e.g.:

  "results": [
      "packages": [
          "package": {
            "name": "",
            "commit": "9a6bd55c9d0722cb101fe85a3b22d89e4ff4fe52"
          "package": {
            "name": "react",
            "version": "1.2.3",
            "ecosystem": "npm"
        // ...

Then pass this to osv-scanner with this:

osv-scanner --lockfile osv-scanner:/path/to/osv-scanner.json
