Creator Network Security Audit Checklist

Phase 3: Testing & Validation

🔐 Authentication & Authorization

  • JWT Validation

    • All protected endpoints require valid JWT token
    • Expired tokens are rejected
    • Invalid/malformed tokens return 401
    • Token claims are validated before processing

  • User Context Extraction

    • user_id is extracted from Supabase auth context (not request body)
    • User cannot access/modify other users' data
    • Session invalidation works properly on logout

  • Authorization Checks

    • Creator can only update their own profile
    • Opportunity creator can only update their own opportunities
    • Applicant can only withdraw their own applications
    • Only opportunity creator can review applications
    • DevConnect links are user-specific

🛡️ Row Level Security (RLS) Policies

  • aethex_creators table

    • Users can read own profile
    • Users can update own profile
    • Public profiles are discoverable (is_discoverable=true)
    • Private profiles (is_discoverable=false) are hidden from directory

  • aethex_opportunities table

    • Anyone can read open opportunities
    • Only creator can update/delete own opportunities
    • Closed opportunities not visible to applicants

  • aethex_applications table

    • Users can read their own applications
    • Applicant can only see their own applications
    • Opportunity creator can see applications for their opportunities
    • Users cannot access others' applications

    • Users can only modify their own projects

🔒 Data Protection

  • Sensitive Data

    • Passwords are never returned in API responses
    • Email addresses are not exposed in public profiles
    • Private notes/applications are not leaked

  • Cover Letters

    • Only applicant and opportunity creator can see cover letters
    • Cover letters are not visible in search results

  • Rate Limiting

    • Rate limiting is implemented on POST endpoints
    • Prevents spam applications/profiles
    • Prevents brute force attacks on search

🚫 Input Validation & Sanitization

  • Text Fields

    • Bio/description max length enforced (e.g., 500 chars)
    • Username format validated (alphanumeric, dashes, underscores)
    • HTML/script tags are escaped in output

    • No malicious file types accepted
    • File size limits enforced

  • Array Fields

    • Skills array has max length
    • Arm affiliations are from valid set
    • Invalid values are rejected

  • Numeric Fields

    • Salary values are reasonable ranges
    • Page/limit parameters are validated
    • Negative values rejected where inappropriate
