**Issue**: Cross-Tenant Validation Not Implemented

**Issue**: Cross-Tenant Validation Not Implemented ~~(OPEN)~~ **(CLOSED)**
|
||||
|
||||
**Details**:
|
||||
- Users from Tenant A can currently access `/api/tenants/B/users` and receive 200 OK
|
||||
**Original Problem**:
|
||||
- Users from Tenant A could access `/api/tenants/B/users` and receive 200 OK
|
||||
- No validation that route `{tenantId}` matches user's JWT `tenant_id` claim
|
||||
- This allows unauthorized cross-tenant data access

- This allowed unauthorized cross-tenant data access

**Impact**: HIGH - Users can access other tenants' user lists
|
||||
**Impact**: HIGH - Users could access other tenants' user lists
|
||||
|
||||
**Recommendation**:
|
||||
1. Implement `RequireTenantMatch` authorization policy
|
||||
2. Validate route `{tenantId}` matches JWT `tenant_id` claim
|
||||
3. Return 403 Forbidden for tenant mismatch
|
||||
4. Apply to all tenant-scoped endpoints
|
||||
**Fix Implemented** (2025-11-03):
|
||||
1. ✅ Added tenant validation to all Role Management endpoints
|
||||
2. ✅ Extract `tenant_id` from JWT claims and compare with route `{tenantId}`
|
||||
3. ✅ Return 403 Forbidden for tenant mismatch
|
||||
4. ✅ Applied to: ListUsers, AssignRole, RemoveUser endpoints
|
||||
|
||||
**Test Status**: Skipped with detailed documentation for Day 7+ implementation
|
||||
**Implementation Details**:
|
||||
```csharp
|
||||
// Added to all endpoints in TenantUsersController.cs
|
||||
var userTenantIdClaim = User.FindFirst("tenant_id")?.Value;
|
||||
if (userTenantIdClaim == null)
|
||||
return Unauthorized(new { error = "Tenant information not found in token" });
|
||||
|
||||
var userTenantId = Guid.Parse(userTenantIdClaim);
|
||||
if (userTenantId != tenantId)
|
||||
return StatusCode(403, new { error = "Access denied: You can only manage users in your own tenant" });
|
||||
```
|
||||
|
||||
**Test Verification**: ✅ All 5 cross-tenant security tests passing
|
||||
- Modified file: `src/ColaFlow.API/Controllers/TenantUsersController.cs`
|
||||
- Test results: 100% pass rate on cross-tenant blocking tests
|
||||
- Documentation: `SECURITY-FIX-CROSS-TENANT-ACCESS.md`, `CROSS-TENANT-SECURITY-TEST-REPORT.md`

## Security Fix Update (2025-11-03)
|
||||
|
||||
### What Was Fixed
|
||||
The critical cross-tenant validation security gap has been completely resolved with the following deliverables:
|
||||
|
||||
1. **Code Changes**: Modified `src/ColaFlow.API/Controllers/TenantUsersController.cs` to add tenant validation to all 3 endpoints
|
||||
2. **Security Tests**: Added 5 comprehensive integration tests in `RoleManagementTests.cs`
|
||||
3. **Documentation**: Created `SECURITY-FIX-CROSS-TENANT-ACCESS.md` and `CROSS-TENANT-SECURITY-TEST-REPORT.md`
|
||||
|
||||
### Test Results After Fix
|
||||
- **Total Tests**: 51 (up from 46)
|
||||
- **Passed**: 46 (up from 41)
|
||||
- **Skipped**: 5 (same as before - blocked by missing user invitation feature)
|
||||
- **Failed**: 0
|
||||
- **Security Tests Pass Rate**: 100% (5/5 tests passing)
|
||||
|
||||
### Files Modified
|
||||
1. `src/ColaFlow.API/Controllers/TenantUsersController.cs` - Added tenant validation
|
||||
2. `tests/Modules/Identity/ColaFlow.Modules.Identity.IntegrationTests/Identity/RoleManagementTests.cs` - Added 5 security tests
|
||||
3. `colaflow-api/DAY6-TEST-REPORT.md` - Updated with security fix verification (this file)
|
||||
|
||||
### Impact
|
||||
✅ Users can no longer access other tenants' data via the Role Management API
|
||||
✅ All cross-tenant requests properly return 403 Forbidden with clear error messages
|
||||
✅ Same-tenant requests continue to work as expected (verified with regression tests)
|
||||
|
||||
**Security Status**: ✅ **SECURE** - Cross-tenant access control fully implemented and tested
