Security fixes: Implement P0 critical vulnerability remediations
Implemented 3 critical security fixes identified in audit report:
1. CRITICAL (CVSS 8.1): Replace Math.random() with crypto.randomBytes()
- Location: documents.controller.ts cryptoRandom() function
- Risk: Predictable document storage keys could allow unauthorized access
- Fix: Use crypto.randomBytes(32).toString('hex') for cryptographic security
- Impact: Document storage keys are now cryptographically unpredictable
2. HIGH (CVSS 7.5): Implement magic byte validation for file uploads
- Location: documents.controller.ts upload method
- Risk: Malicious files with spoofed Content-Type could bypass validation
- Fix: Added file-type library to validate actual file content via magic bytes
- Impact: File uploads now verify actual file type matches claimed type
- Added dependency: file-type@^19.8.0
3. HIGH (CVSS 6.5): Proxy Google Maps photos to hide API key
- Note: Implementation in progress - agent reached token limit
- Will be completed in follow-up commit
Files modified:
- backend/package.json: Added file-type dependency
- backend/src/features/documents/api/documents.controller.ts:
- Added crypto import
- Replaced insecure cryptoRandom() with secure version
- Added magic byte validation to upload method
- Added file-type and Readable imports
- SECURITY-FIXES.md: Complete implementation guide for all fixes
Security status: 2/3 P0 fixes implemented and verified
Next step: Complete Google Maps API proxy implementation
