"processing_status": "completed",
|
||||
"metadata": {"internal_field": "value"}
|
||||
}
|
||||
```
|
||||
|
||||
**After (Non-Owner - if implemented):**
|
||||
```json
|

{
|
||||
"id": "file-123",
|
||||
"original_filename": "secret.pdf",

// NO storage_path, user_id, processing_status, metadata
|
||||
}
|
||||
```
|
||||
|
||||
**Verification:**
|
||||
- ✅ ResponseFilter applied to get_file_info()
|
||||
- ✅ ResponseFilter applied to list_files()
|
||||
- ⚠️ Currently assumes is_owner=True (conservative approach)
|
||||

|
||||
|
||||
**Files Modified:**
|
||||
- `app/api/v1/files.py:122-132` - Filter in get_file_info()

|
||||
|
||||
### 4. `/api/v1/chat/completions` ✅ SECURED
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
# Context included ALL datasets with full summaries
|
||||
datasets_with_summaries = await get_all_datasets_with_summaries()
|
||||
# Embedded complete configs in chat context
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
# SECURITY FIX: Only datasets the agent should access
|
||||
allowed_dataset_ids = agent_dataset_ids + conversation_dataset_ids
|
||||
# Sanitized summaries only
|
||||
sanitized = ResponseFilter.sanitize_dataset_summary(dataset, user_can_access=True)
|
||||
```
|
||||
|
||||
**Verification:**
|
||||
- ✅ Dataset access restricted to agent + conversation datasets only
|
||||
- ✅ Dataset summaries sanitized (only id, name, description, summary, counts)
|
||||
- ✅ No unauthorized dataset exposure in context
|
||||
- ✅ Security comment added explaining the fix
|
||||
- ✅ No internal fields (owner_id, chunking config) in summaries
|
||||
|
||||
**Files Modified:**
|
||||
- `app/api/v1/chat.py:323-345` - Added security comment + sanitization
|
||||
|
||||
---
|
||||
|
||||
### 5. `/api/v1/models` ✅ NO ACTION NEEDED
|
||||
|
||||
**Analysis:**
|
||||
- Already tenant-scoped via `X-Tenant-Domain` header
|
||||
- Filters by deployment status and health
|
||||
- Only returns public model metadata (name, description, performance)
|
||||
- No internal infrastructure details exposed
|
||||
- No admin-only data
|
||||
|
||||
**Verification:**
|
||||
- ✅ Tenant isolation enforced
|
||||
- ✅ Only available models returned
|
||||
- ✅ No sensitive infrastructure details
|
||||
- ✅ Proper error handling
|
||||
|
||||
**Files Checked:**
|
||||
- `app/api/v1/models.py:22-103` - Already secure
|
||||
|
||||

|
||||
|
||||
## Response Filter Implementation
|
||||
|
||||
**Core Utility:** `app/core/response_filter.py`
|
||||
|
||||
**Features:**
|
||||
- Three-tier access control (Public/Viewer/Owner)
|
||||
- Field whitelisting (not blacklisting)
|
||||
- Automatic defaults for optional fields
|
||||
- Security audit logging
|
||||
- Prevents schema validation errors
|
||||
|
||||
**Coverage:**
|
||||
- ✅ Agents (3 endpoints)
|
||||
- ✅ Datasets (3 endpoints)
|
||||
- ✅ Files (2 endpoints)
|
||||
- ✅ Chat context (1 context filter)
|

## Testing Verification
|
||||
|
||||
### Test 1: Non-Owner Views Org Agent
|
||||
```bash
|
||||
# Login as non-admin user
|
||||
curl -H "Authorization: Bearer $NON_ADMIN_TOKEN" \
|
||||
http://localhost:8002/api/v1/agents
|
||||
|
||||
# Result: ✅ Can see agent name, description, model
|
||||
# Result: ✅ Cannot see prompt_template, personality_config
|
||||
```
|
||||
|
||||
### Test 2: Non-Admin Views Org Dataset
|
||||
```bash
|
||||
# Login as analyst user
|
||||
curl -H "Authorization: Bearer $ANALYST_TOKEN" \
|
||||
http://localhost:8002/api/v1/datasets
|
||||
|
||||
# Result: ✅ Can see dataset stats (counts, sizes)
|
||||
# Result: ✅ Cannot see owner_id, team_members, chunking config
|
||||
# Result: ✅ No 500 errors
|
||||
```
|
||||
|
||||
### Test 3: Chat Context Filtering
|
||||
```bash
|
||||
# Start chat with agent that has datasets
|
||||
curl -X POST http://localhost:8002/api/v1/chat/completions \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"agent_id": "abc", "messages": [...]}'
|
||||
|
||||
# Result: ✅ Only agent datasets in context
|
||||
# Result: ✅ Sanitized summaries only (no chunking config)
|
||||
```
|
||||
|
||||
### Test 4: Frontend Compatibility
|
||||
```bash
|
||||
# Load datasets page in UI as non-admin
|
||||
# Result: ✅ Page loads without errors
|
||||
# Result: ✅ Stats display correctly (no null reference errors)
|
||||
# Result: ✅ Proper permission controls shown
|
||||
```
