Supply Chain Scanner

Overview

The supply chain scanner analyzes your project’s dependency manifests for risks that could allow an attacker to inject malicious code during a build. It runs on scan repo and scan github targets.

Checks

Lockfile check

Severity: HIGH | Confidence: 85% Detects projects that declare dependencies without a lockfile. Without a lockfile, npm install or pip install can silently install different versions on each run — including versions with newly disclosed vulnerabilities. Detected for:

npm: missing package-lock.json or yarn.lock or pnpm-lock.yaml
Python: missing Pipfile.lock or poetry.lock (when Pipfile or pyproject.toml exists)

# Fix for npm
npm install          # generates package-lock.json
git add package-lock.json && git commit -m "Add npm lockfile"

# Fix for yarn
yarn install         # generates yarn.lock

# Fix for Python (poetry)
poetry lock          # generates poetry.lock

Floating version check (npm)

Severity: MEDIUM | Confidence: 75% Detects npm packages declared with floating version ranges (^, ~, *, latest). These ranges allow patch and minor updates to be pulled in automatically, which can introduce breaking changes or compromised packages.

// package.json — flagged
{
  "dependencies": {
    "express": "^4.18.0",    // Any 4.x version OK
    "lodash": "~4.17.0",     // Any 4.17.x OK
    "axios": "*"              // Any version OK — HIGH risk
  }
}

# Fix: pin all versions
npm install --save-exact express lodash axios
# Or manually set exact versions and commit package-lock.json

Dependency confusion check

Severity: HIGH | Confidence: 70% Detects package names that look like internal scoped packages (@company/internal-tool) but may not be published to the public npm registry. Dependency confusion attacks trick package managers into downloading a malicious public package with the same name as an internal one. How it works: The scanner flags scoped packages (@org/name) and checks if the organization namespace could be registered publicly. It also looks for import patterns that suggest private registry use without explicit registry configuration. Remediation:

# Add .npmrc to lock to your private registry
@mycompany:registry=https://registry.mycompany.com/
# Or use npm publish to "claim" the namespace on npmjs.com

CVE check (OSV.dev)

Severity: Varies | Confidence: 90% When --check-cves is passed, ZenVeil queries the Open Source Vulnerabilities database for known CVEs in your pinned dependencies. This requires network access.

zenveil scan repo . --check-cves
zenveil scan github owner/repo --check-cves

Supported ecosystems:

npm (package-lock.json)
PyPI (requirements.txt, Pipfile.lock, poetry.lock)

Example finding:

ID:          ZG-B2C3D4
Severity:    HIGH
Title:       Known CVE in dependency
Scanner:     supply_chain
Evidence:    lodash@4.17.20 is affected by CVE-2021-23337 (Prototype Pollution)
Remediation: Upgrade lodash to 4.17.21 or later.

Why supply chain security matters

The 2020 SolarWinds attack compromised 18,000 organizations by injecting malicious code into a software build pipeline. The 2021 ua-parser-js attack affected millions of projects when an attacker published a malicious version of a popular npm package. The colors and faker incidents showed how a single maintainer decision can sabotage thousands of downstream projects. Your supply chain is only as secure as your weakest dependency. ZenVeil gives you visibility before it’s a headline.
