Full-Stack Bug Bounty Platform

Overview

Build a comprehensive web application connecting security researchers with organizations for coordinated vulnerability disclosure, including submission workflows, severity scoring, payment management, and encrypted communications. This project teaches full-stack web development, vulnerability management processes, and demonstrates platforms like HackerOne and Bugcrowd.

Step-by-Step Instructions

1. Understand bug bounty ecosystem and platform requirements by learning that bug bounty platforms connect researchers ("hackers") with organizations ("customers") paying for vulnerability discoveries. Study platform features: researcher onboarding and reputation systems, organization program setup and scope management, vulnerability submission workflows with status tracking, severity assessment using CVSS, reward management and payments, and communication systems. Research existing platforms (HackerOne, Bugcrowd, Intigriti) understanding features and market differentiation.

2. Design user roles and authentication system with three primary roles: researchers (submit vulnerabilities, earn rewards), organizations (run programs, review submissions), and administrators (platform management). Implement authentication: email/password signup, email verification, two-factor authentication for security, OAuth integration enabling social login. Build role-based access control (RBAC) restricting capabilities by role (researchers can't approve reports, organizations can't approve their own reports).

3. Build researcher management and reputation system implementing researcher profiles showing: submitted vulnerabilities, accepted reports, rewards earned, reputation score, and profile verification badges. Create reputation calculation: points for discovered vulnerabilities (more points for higher severity), community engagement (forum participation, report quality), and tiered levels (green, white, expert researcher) enabling companies to filter by researcher quality. Implement researcher discovery: organizations can search/filter researchers by expertise, previous findings, and reliability.

4. Create vulnerability submission workflow building comprehensive report submission process: researchers submit vulnerabilities with title, description, affected component, reproduction steps, and supporting files (screenshots, proof-of-concept). Implement CVSS calculator letting researchers estimate severity, then have organization confirm. Build report status tracking (submitted → triage → accepted/rejected → rewards payment, or duplicate). Implement escalation process for disputes about severity/acceptance.

5. Build encrypted communications system enabling secure discussion between researchers and organizations about vulnerabilities: create threaded conversations with encryption ensuring sensitive information remains confidential, implement temporary access links preventing unauthorized access, and build audit trails logging all communications for dispute resolution. Implement communication history enabling researchers to reference previous discussions.

6. Implement severity assessment and scoring using CVSS (Common Vulnerability Scoring System): build calculator accepting CVSS inputs (attack vector, complexity, privileges required, impact), computing scores automatically. Create mapped rewards: different severity levels have associated reward ranges (Critical: $5000-$10000, High: $2000-$4999, etc.), allowing organizations to set specific ranges. Implement reward negotiation: organizations offer bounties, researchers can accept/negotiate, creating binding agreements.

7. Create payment and reward management building reliable payment system: integrate payment gateways (Stripe, PayPal) processing researcher payouts, implement escrow protecting both parties (organization funds held until resolution), calculate taxes and handle 1099 reporting for US researchers, and provide payment history/tracking. Build invoicing system enabling researchers to create invoices for accepted bounties. Implement payout scheduling with confirmation workflows.

8. Build comprehensive platform with organization program management, dashboard, and reporting enabling organizations to: create bug bounty programs specifying scope (in-scope domains/assets, out-of-scope), set rules of engagement (testing permissions, disclosure policy), manage severity scoring and reward budgets, view vulnerability status dashboard. Implement researcher dashboards showing submitted reports, earnings, and leaderboard standings. Build analytics: organizations see trends (vulnerability types, researcher quality, time-to-fix), researchers see opportunities and market rates. Create compliance features: secure disclosure timelines (coordinated vulnerability disclosure), export for compliance documentation. Compare your platform to HackerOne/Bugcrowd discussing differentiation, limitations (building trust and critical mass of researchers is challenging), and regulatory considerations (ensure compliance with employment laws, tax regulations, payment regulations across jurisdictions).
