SBOM Security Scanner

Generate, scan, fix, trace & review — all 6 phases in one click

1

Generate SBOM

Create CycloneDX bill of materials from package-lock.json

2

Vulnerability Scan

Scan SBOM against Trivy CVE database for known vulnerabilities

3

Fix Vulnerabilities

Auto-fix safe upgrades, re-generate SBOM, show remaining risks

4

Dependency Tree

Trace who pulls in each package — find hidden transitive chains

5

License Compliance

Review all licenses — flag copyleft, unknown, or risky terms

6

Full Report

Combined security posture summary — ready to share with app owner

External SBOM Scanner

Scan bug bounty targets — upload SBOMs, dependency files, or scan GitHub repos & live URLs

Target Name

Platform

Upload File SBOM (CycloneDX/SPDX) or dependency files (package-lock.json, requirements.txt, pom.xml, etc.)

Paste Content CycloneDX JSON, SPDX JSON, requirements.txt, or JSON package list

Manual Packages Enter package names and versions you know about the target

GitHub Repo Auto-fetch dependency files from a public repository

Fingerprint URL Detect tech stack from HTTP headers and HTML source (passive only)

Submit an input first, then results appear here.

Scan a target first to generate a report.

Fast Start

Pick the input method based on what you have: file, pasted SBOM, manual package list, GitHub repo, or live URL.
Fill Target Name and Platform first so the result is easier to report later.
Process the input, then click Scan for vulnerabilities.
Review Results for CVEs, severity, affected package, and fix version.
Open Report to copy a professional bug bounty write-up.
Use History to re-run scans after changes or fixes.

Which Input To Use

If you have...	Use	Why
A real SBOM file from a target	Upload File	Best accuracy. Fastest path to CVEs.
Raw CycloneDX/SPDX text	Paste Content	No need to save a file locally.
Only package names and versions	Manual Packages	Good for screenshots, docs, or disclosed stack info.
A public GitHub repository	GitHub Repo	Auto-pulls package files and builds the SBOM.
Only the live website URL	Fingerprint URL	Passive detection from headers and HTML only.

End-to-End Workflow

1

Find the dependency evidence

Look for package manifests, SBOM exports, public repos, CDN URLs, disclosure docs, or platform-provided artifacts. Stay inside program scope and use passive collection first.

2

Build or import the SBOM

The tool converts dependency files into CycloneDX automatically. That gives you a normalized package inventory for scanning and reporting.

3

Scan for vulnerabilities

Run Trivy to identify CVEs, severity, fix versions, and affected packages. Start with Critical and High findings, then review Medium for exploitability.

4

Validate the finding

Confirm the vulnerable package version is truly present and relevant to the target. Check whether it is runtime-reachable, bundled to production, or only a dev dependency.

5

Document impact and fix

Use the Report tab to capture CVE, package, affected version, fixed version, remediation advice, and methodology. Add program-specific impact only if you can support it.

6

Re-scan after remediation

Run the same target again from History after a dependency change, new SBOM, or new repo state. Compare vulnerability counts before and after to prove the fix.

What To Check In Results

Severity: Prioritize Critical and High first.
Package and version: Verify exact affected version is present.
Fix version: Check if an upgrade path exists.
CVE details: Review the advisory before reporting.
Reachability: Decide whether the package is actually exposed in the target.
License risk: Watch for copyleft or unknown licenses in enterprise reviews.

How To Fix And Re-Scan

Upgrade the dependency to the fixed version shown in Results or Report.
If no fix exists, replace the package, remove the feature, or isolate the risk.
Generate a new SBOM after dependency changes.
Run the same scan again from History to confirm the vulnerability count dropped.
Keep both pre-fix and post-fix scan results as evidence for engineering or for closure notes.

Common Mistakes

Reporting a CVE without confirming the exact version is used.
Treating dev-only dependencies as production impact without proof.
Using active techniques outside bug bounty scope.
Claiming exploitability when you only proved package presence.
Skipping re-scan after a dependency update.

Reporting Checklist

Target name and platform filled in

Input source captured: file, repo, or URL

CVE ID linked to advisory

Affected package and version verified

Fix version or workaround documented

Report copied from the Report tab

Re-scan performed after any fix

Program scope respected throughout
