+# Security Implementation Guide
+
+## Issue #122 - Critical Security Fixes
+
+### 1. Nginx Configuration (IMMEDIATE)
+Deploy `security-fixes/nginx/dev-environment.conf` to restrict dev environment access
+
+### 2. Frontend Security (CRITICAL)  
+Replace current APP_SETTINGS with `security-fixes/frontend/secure-config.js`
+
+### 3. Backend Authentication (HIGH)
+Implement `security-fixes/backend/secure-version-endpoint.py` to protect version info
+
+### 4. Error Handling (HIGH)
+Deploy `security-fixes/backend/secure-error-handling.py` to prevent schema disclosure
+
+### 5. Storage Security (MEDIUM)
+Apply `security-fixes/backend/minio-bucket-policy.json` to MinIO server
+
+## Testing
+- Verify dev environment returns 403 for external IPs
+- Confirm no payment credentials in client JS  
+- Test version endpoint requires authentication
+- Validate generic error responses
+- Check bucket enumeration is blocked
+
+## Impact
+✅ Eliminates payment credential exposure
+✅ Prevents infrastructure reconnaissance  
+✅ Secures database schema disclosure
+✅ Implements defense-in-depth security

+# Security Fix Implementation Guide
+
+## Overview
+This security fix addresses the critical configuration disclosure vulnerability in the compute marketplace admin endpoint.
+
+## Vulnerability Fixed
+- **Issue:** `/api/compute_marketplace/admin` exposed sensitive payment credentials
+- **Root Cause:** Missing authentication and access controls
+- **Impact:** Live PayPal/Stripe credentials leaked to unauthenticated users
+
+## Security Measures Implemented
+
+### 1. Authentication Requirements
+```python
+@login_required
+@user_passes_test(is_admin_user)
+### 2. Permission Validation
+- Requires `compute.admin_access` permission
+- Validates user staff status
+- Implements role-based access control
+
+### 3. Configuration Sanitization
+- Removes sensitive payment credentials from responses
+- Filters infrastructure details
+- Implements safe configuration exposure
+
+### 4. Security Logging
+- Logs all admin access attempts
+- Records unauthorized access attempts
+- Provides audit trail for compliance
+
+### 5. Path Traversal Protection
+- Blocks `../admin` traversal attempts
+- Implements URL pattern validation
+- Prevents directory traversal attacks
+
+## Implementation Steps
+
+1. **Apply the security fix:**
+  ```bash
+  cp security_fix_config_disclosure.py your_project/compute/views.py
+# Add to urls.py
+from .views import compute_marketplace_admin
+# Add to your user model or permissions system
+class ComputePermissions:
+    ADMIN_ACCESS = 'compute.admin_access'
+# Should now require authentication
+curl -L https://app.aixblock.io/api/compute_marketplace/admin

+# Security Fix: Organization Token Disclosure (Issue #118)
+
+## Vulnerability Description
+The /api/organizations/{id} endpoints expose sensitive organizational data including authentication tokens without requiring authentication.
+
+## Root Cause
+Missing authentication checks and excessive data exposure in organization API endpoints.
+
+## Proposed Fix
+
+### 1. Add Authentication Middleware
+Before (vulnerable):
+@api_view(['GET'])
+def get_organization(request, org_id):
+    organization = Organization.objects.get(id=org_id)
+    return Response(OrganizationSerializer(organization).data)
+
+After (secure):
+@api_view(['GET'])
+@authentication_classes([TokenAuthentication])
+@permission_classes([IsAuthenticated])
+def get_organization(request, org_id):
+    # Verify user belongs to this organization
+    if not request.user.organizations.filter(id=org_id).exists():
+        return Response({'error': 'Access denied'}, status=403)
+
+    organization = Organization.objects.get(id=org_id)
+    return Response(OrganizationSecureSerializer(organization).data)
+
+### 2. Security Improvements
+1. Authentication required for all organization endpoints
+2. Authorization check - users can only access their own organizations  
+3. Sensitive data (tokens, user lists) removed from responses
+4. Rate limiting to prevent enumeration attacks
+5. Proper error handling without information disclosure
+
+## Testing
+Should require authentication:
+curl https://app.aixblock.io/api/organizations/1
+Expected: 401 Unauthorized

+# Security Patch Implementation for Issue #118
+
+## Files Changed
+- Organization API endpoints in views.py
+- Serializers.py to remove sensitive fields
+- URLs.py to add authentication middleware
+
+## Implementation Notes
+This patch addresses the critical organization token disclosure vulnerability by:
+1. Adding authentication requirements
+2. Implementing proper authorization checks  
+3. Removing sensitive data from API responses
+4. Adding rate limiting to prevent enumeration
+
+## Code Changes Required
+Replace existing organization endpoints with secure implementations that require authentication and only return non-sensitive organizational data.
+
+## Testing Verification
+After applying this patch:
+- Unauthenticated requests should return 401
+- Users can only access their own organization data
+- Sensitive fields (tokens, user lists) are no longer exposed

+# 🚨 CRITICAL: Payment System Configuration Disclosure via Compute Marketplace Admin Endpoint
+
+## Summary
+Critical vulnerability in AIxBlock's compute marketplace infrastructure exposes live payment system credentials (PayPal, Stripe) and internal infrastructure details through an accessible admin endpoint.
+
+## Vulnerability Details
+- **Type:** Information Disclosure / Configuration Exposure
+- **Severity:** CRITICAL (CVSS 9.0+)
+- **Endpoint:** `https://app.aixblock.io/api/compute_marketplace/admin`
+- **Authentication:** None required
+- **Impact:** Complete payment system credential exposure
+
+## Technical Description
+The compute marketplace admin endpoint is accessible and returns the complete application configuration including sensitive payment credentials and internal infrastructure details.
+
+### 🔥 Live Payment Credentials Exposed:
