**Scan Date:** 2026-01-02 02:46:06 UTC
**Results File:** `codeql-results-js.sarif` (797K)
**Critical Findings:** 0 errors
**Status:** ✅ PASSED
### Summary
Both Go and JavaScript/TypeScript security scans completed successfully with **zero critical security vulnerabilities** detected in the application code.

## Change Summary
### What Was Fixed
The backend IP validation logic was updated to properly handle IP address parsing and validation:
1. **IP Parsing Validation:** Enhanced `network.IsValidIPOrCIDR()` to validate IPs before CIDR check
2. **Error Handling:** Improved error handling for invalid IP formats
3. **Type Safety:** Ensured consistent handling of IP types (IPv4/IPv6)
### Files Modified
- `backend/internal/network/` - IP validation utilities
- Related handler logic for IP-based operations
### Tests Passed
- All existing unit tests continue to pass
- Coverage maintained above 85% threshold
- No regressions detected
---
## Approval
Based on the comprehensive QA validation:
- ✅ Backend coverage: **85.8%** (exceeds 85% threshold)
- ✅ TypeScript compilation: **No errors**
- ✅ Pre-commit hooks: **All passed**
- ✅ CodeQL security scans: **Zero critical findings**
**Final Status:****APPROVED FOR COMMIT**
**Next Steps:**
1. Commit changes with appropriate message
2. Push to feature branch
3. Create pull request for review
