OSV-Scanner

Trigger / When to Use

Use this skill when the user wants a fast open-source dependency vulnerability scan based on the OSV database, especially for projects with lockfiles, package manifests, SBOMs, or git repositories.

Good trigger phrases:

• "scan dependencies with OSV"
• "check package-lock or go.sum for CVEs"
• "find vulnerable open-source packages"
• "scan this SBOM against OSV"
• "add OSV scanning to CI"

Core Capabilities

• Scan source directories and automatically discover lockfiles, SBOMs, and git metadata.
• Scan specific package manifests or lockfiles.
• Scan SPDX or CycloneDX SBOMs.
• Report vulnerabilities from the OSV database across language ecosystems.
• Work well as a lightweight SCA gate in CI.
• Provide actionable package names, versions, vulnerability IDs, and fixed versions when available.

Workflow

1. Confirm Scope

Determine whether the user wants to scan:

• The current repository.
• A single manifest or lockfile.
• An SBOM file.
• A monorepo with multiple package roots.
• Git history or checked-out code only.

Prefer scanning lockfiles when present because they represent resolved dependency versions.

2. Verify Installation

osv-scanner --version

If it is missing, recommend the official OSV-Scanner installation method for the user's platform.

3. Run Source Scan

Use source scanning for normal repositories:

osv-scanner scan source .

Scan a specific lockfile or manifest:

osv-scanner scan source --lockfile package-lock.json .

Scan an SBOM:

osv-scanner scan source -L sbom.spdx.json .

4. Capture JSON Output

Use JSON when the result needs to feed automation:

osv-scanner scan source --format json --output osv-results.json .

If the installed version does not support a flag exactly as written, run osv-scanner --help and adapt to the installed CLI syntax.

5. Triage Results

For each finding, record:

• Package name and ecosystem.
• Vulnerable version.
• Introduced and fixed version ranges.
• Vulnerability aliases such as CVE or GHSA.
• Whether the package is direct or transitive.
• Owning package manager and lockfile path.

Prioritize:

1. Direct dependencies with fixed versions.
2. Transitive vulnerabilities reachable through active runtime paths.
3. Vulnerabilities with public exploit references.
4. Dependencies used in production builds over dev-only packages.

6. Remediation Strategy

Use the package manager native workflow first:

npm audit fix
go get module@example.com@patched-version
pip-compile --upgrade-package package-name
cargo update -p package-name
bundle update package-name

When no fixed version exists:

• Check whether the vulnerable feature is used.
• Consider temporary dependency replacement.
• Add a short-lived ignore entry with reason and review date.
• Open an upstream issue if the package is still maintained.

Common Patterns

GitHub Actions Gate

name: osv-scanner
on: [pull_request]
jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Install OSV-Scanner
        run: go install github.com/google/osv-scanner/v2/cmd/osv-scanner@latest
      - name: Scan dependencies
        run: osv-scanner scan source .

Monorepo Scan Checklist

1. List package roots and lockfiles.
2. Scan from repository root.
3. Re-run targeted scans for high-risk services.
4. Deduplicate repeated findings by package/version/vulnerability ID.
5. Assign owners based on package root.

Finding Template

## OSV Finding

- Package:
- Ecosystem:
- Current version:
- Fixed version:
- Vulnerability:
- Direct/transitive:
- Lockfile:
- Recommended action:
- Risk owner:

Interpretation Rules

• Lockfile findings are usually more reliable than manifest-only findings.
• Development-only dependencies may still matter if they run in CI, build scripts, or release automation.
• A vulnerable transitive dependency should be fixed through the top-level package when possible.
• Do not delete lockfiles to reduce findings; that lowers reproducibility.
• Compare OSV findings with another scanner when results affect a release block.

Boundaries

• OSV-Scanner is not a full SAST tool.
• It does not prove runtime exploitability.
• It should not be the only scanner for container images or Linux host packages.
• Do not publish private dependency inventories without approval.
• Do not blanket-ignore entire ecosystems or package managers.
