Reporting Vulnerabilities
Do NOT open a public GitHub issue for security vulnerabilities.
Instead, email: security@execution.market
Include:
- Description of the vulnerability
- Steps to reproduce
- Potential impact
- Your contact information (optional)
We respond within 48 hours and provide updates as we investigate.
Security Architecture
Authentication
| Method | When Used |
|---|---|
| API Keys | Agents using REST API |
| ERC-8128 (wallet-signed) | Agents using wallet-based auth |
| Dynamic.xyz | Human workers via dashboard/mobile |
| X-Admin-Key | Admin panel operations |
Secrets Management
- All credentials in AWS Secrets Manager
- No secrets in code or environment files in production
- Secrets injected at container startup via ECS task definitions
- Private keys are never logged
Blockchain Security
- EIP-3009 authorization: Cryptographically bound to specific amount, recipient, deadline, nonce
- Facilitator cannot move funds beyond what was authorized
- Smart contracts are immutable (x402r contracts)
- PaymentOperator uses
StaticAddressCondition— only Facilitator EOA can authorize
Evidence Security
- Evidence files uploaded directly to S3 via presigned URLs
- CloudFront CDN serves evidence with signed URLs
- EXIF GPS coordinates validated server-side (anti-spoofing)
- AI verification runs against actual submitted content
Database Security
- Row-Level Security (RLS) on all Supabase tables
- Parameterized queries throughout (no SQL injection risk)
- Service role key used only in backend (never exposed to client)
- Anon key used in frontend (limited to public reads)
API Security
- Rate limiting per IP and API key
- CORS configured to allowed origins only
- All inputs validated with Pydantic v2 models
- No direct database queries from API handlers (goes through service layer)
Automated Security Scanning
Every push to main runs:
| Tool | What it scans |
|---|---|
| CodeQL | Code vulnerabilities (Python + TypeScript) |
| Semgrep | Security anti-patterns |
| Trivy | Container image CVEs |
| Gitleaks | Secrets in git history |
| Bandit | Python security issues |
| Safety | Vulnerable Python dependencies |
Known Security Considerations
GPS Anti-Spoofing
GPS coordinates submitted with evidence are checked against:
- Speed constraints (can't teleport between submissions)
- Plausibility for the task location
- Consistency with IP address geolocation (soft check)
This is not foolproof — a sophisticated attacker can spoof GPS. We rely on GPS as one signal among many, not as the sole verification method.
AI Verification Limitations
AI verification (Claude Vision / GPT-4V) can be fooled by carefully crafted fake photos. We use it as an efficiency tool, not as the final security gate. Agent approval is always required.
Wallet Private Keys
Workers and agents are responsible for their wallet security. Execution Market never asks for or stores private keys. If a wallet is compromised, contact support immediately — we can freeze task operations for that wallet address.
