# Security Fix: API Response Filtering - Final Summary
|
||||
|
||||
**Date**: 2025-10-03
|
||||
**Severity**: HIGH (Information Disclosure)
|
||||
**Status**: ✅ FIXED & TESTED
|
||||
|
||||
---
|
||||
|
||||
## Vulnerability
|
||||
|
||||
API endpoints (`/agents`, `/datasets`, `/files`, `/chat/completions`) were returning excessive sensitive data without proper server-side filtering:
|
||||
|
||||
- ❌ System prompts and AI instructions exposed to non-owners
|
||||
- ❌ Internal configuration (personality_config, resource_preferences)
|
||||
- ❌ User UUIDs and team member lists
|
||||
- ❌ Infrastructure details (embedding models, chunking strategies)
|
||||
- ❌ Unauthorized dataset summaries in chat context
|
||||
|
||||
---
|
||||
|
||||
## Solution Implemented
|
||||
|
||||
### 1. Response Filtering Utility (`app/core/response_filter.py`)
|
||||
|
||||
Created three-tier access control with field-level filtering:
|
||||
|
||||
**Agents:**
|
||||
- **Public**: id, name, description, category, model, disclaimer, easy_prompts, metadata
|
||||
- **Viewer**: Public + temperature, max_tokens, costs
|
||||
- **Owner**: Viewer + prompt_template, personality_config, resource_preferences, dataset_connection
|
||||
|
||||
**Datasets:**
|
||||
- **Public**: id, name, description, stats (counts, size), tags, dates, created_by_name
|
||||
- **Viewer**: Public + summary
|
||||
- **Owner**: Viewer + owner_id, team_members, chunking config, embedding_model
|
||||
|
||||
**Files:**
|
||||
- **Public**: id, filename, content_type, size, timestamps
|
||||
- **Owner**: Public + storage_path, processing_status, metadata
|
||||
|
||||
### 2. Modified Endpoints
|
||||
|
||||
✅ `app/api/v1/agents.py` - Filters responses in `list_agents()` and `get_agent()`
|
||||
✅ `app/api/v1/datasets.py` - Filters in `list_datasets()`, `get_dataset()`
|
||||
✅ `app/api/v1/chat.py` - Sanitizes dataset summaries in context
|
||||
✅ `app/api/v1/files.py` - Filters in `get_file_info()`, `list_files()`
|
||||
|
||||
### 3. Schema Updates
|
||||
|
||||
Updated Pydantic response models to make sensitive fields optional:
|
||||
- `owner_id`, `team_members` → Optional (hidden from non-owners)
|
||||
- `chunking_strategy`, `chunk_size`, `chunk_overlap`, `embedding_model` → Optional (owner-only)
|
||||
- Stats fields (`chunk_count`, `vector_count`, `storage_size_mb`) → **Kept required** (informational, not sensitive)
|
||||
|
||||

|
||||
|
||||
## Security Decisions
|
||||
|
||||
### ✅ What's Hidden from Non-Owners
|
||||
|
||||
**Critical (Never Exposed):**
|
||||
- System prompts (`prompt_template`)
|
||||
- Internal configs (`personality_config`, `resource_preferences`)
|
||||
- User UUIDs (`owner_id`)
|
||||
- Team member lists
|
||||
- Infrastructure configs (chunking, embedding models)
|
||||
|
||||
### ✅ What's Visible to All
|
||||
|
||||
**Safe to Expose:**
|
||||
- Names, descriptions, categories
|
||||
- Document/chunk/vector counts (just statistics)
|
||||
- Storage sizes (informational)
|
||||
- Created dates
|
||||
- Creator names (human-readable, not UUIDs)
|
||||
- Access permissions (for UI controls)
|
||||
|
||||
**Rationale**: Statistics like document count and storage size are informational only. They don't reveal sensitive business logic or allow unauthorized access. Hiding them would break UI functionality without security benefit.

|
||||
|
||||
## Testing Results
|
||||
|
||||
### ✅ Test Case 1: Non-Owner Viewing Org Agent
|
||||
**Before**: Could see full `prompt_template`, `personality_config`, `selected_dataset_ids`
|
||||
**After**: Sees name, description, model, disclaimer - **NO internal configs** ✅
|
||||
|
||||
### ✅ Test Case 2: Non-Admin Viewing Org Dataset
|
||||
**Before**: 500 error due to schema validation
|
||||
**After**: Sees name, stats, created_by_name - **NO owner_id, team_members, chunking config** ✅
|
||||
|
||||
### ✅ Test Case 3: Chat Context Dataset Summaries
|
||||
**Before**: All datasets leaked in context with full metadata
|
||||
**After**: Only agent + conversation datasets, sanitized summaries only ✅
|
||||
|
||||
### ✅ Test Case 4: Frontend Compatibility
|
||||
**Before**: N/A
|
||||
**After**: UI loads correctly, stats display properly, no null reference errors ✅

## Response Size Comparison

||||
|
||||
### Datasets Endpoint (Organization Dataset for Non-Owner)
|
||||
|
||||
**Before (858 bytes):**
|
||||
```json
|
||||

|
||||
