Remove conversation context/recall system from ClaudeTools
Completely removed the database context recall system while preserving database tables for safety. This major cleanup removes 80+ files and 16,831 lines of code. What was removed: - API layer: 4 routers (conversation-contexts, context-snippets, project-states, decision-logs) with 35+ endpoints - Database models: 5 models (ConversationContext, ContextSnippet, DecisionLog, ProjectState, ContextTag) - Services: 4 service layers with business logic - Schemas: 4 Pydantic schema files - Claude Code hooks: 13 hook files (user-prompt-submit, task-complete, sync-contexts, periodic saves) - Scripts: 15+ scripts (import, migration, testing, tombstone checking) - Tests: 5 test files (context recall, compression, diagnostics) - Documentation: 30+ markdown files (guides, architecture, quick starts) - Utilities: context compression, conversation parsing Files modified: - api/main.py: Removed router registrations - api/models/__init__.py: Removed model imports - api/schemas/__init__.py: Removed schema imports - api/services/__init__.py: Removed service imports - .claude/claude.md: Completely rewritten without context references Database tables preserved: - conversation_contexts, context_snippets, context_tags, project_states, decision_logs (5 orphaned tables remain for safety) - Migration created but NOT applied: 20260118_172743_remove_context_system.py - Tables can be dropped later when confirmed not needed New files added: - CONTEXT_SYSTEM_REMOVAL_SUMMARY.md: Detailed removal report - CONTEXT_SYSTEM_REMOVAL_COMPLETE.md: Final status - CONTEXT_EXPORT_RESULTS.md: Export attempt results - scripts/export-tombstoned-contexts.py: Export tool for future use - migrations/versions/20260118_172743_remove_context_system.py Impact: - Reduced from 130 to 95 API endpoints - Reduced from 43 to 38 active database tables - Removed 16,831 lines of code - System fully operational without context recall Reason for removal: - System was not actively used (no tombstoned contexts found) - Reduces codebase complexity - Focuses on core MSP work tracking functionality - Database preserved for safety (can rollback if needed) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# SQL Injection Vulnerability Fixes
|
||||
|
||||
## Status: COMPLETED
|
||||
|
||||
All CRITICAL SQL injection vulnerabilities have been fixed in the code.
|
||||
|
||||
---
|
||||
|
||||
## Vulnerabilities Fixed
|
||||
|
||||
### 1. SQL Injection in search_term LIKE clause
|
||||
**File:** `api/services/conversation_context_service.py`
|
||||
**Lines:** 190-191 (original)
|
||||
|
||||
**Vulnerable Code:**
|
||||
```python
|
||||
ConversationContext.title.like(f"%{search_term}%")
|
||||
ConversationContext.dense_summary.like(f"%{search_term}%")
|
||||
```
|
||||
|
||||
**Fixed Code:**
|
||||
```python
|
||||
ConversationContext.title.like(func.concat('%', search_term, '%'))
|
||||
ConversationContext.dense_summary.like(func.concat('%', search_term, '%'))
|
||||
```
|
||||
|
||||
### 2. SQL Injection in tag filtering
|
||||
**File:** `api/services/conversation_context_service.py`
|
||||
**Line:** 207 (original)
|
||||
|
||||
**Vulnerable Code:**
|
||||
```python
|
||||
ConversationContext.tags.like(f'%"{tag}"%')
|
||||
```
|
||||
|
||||
**Fixed Code:**
|
||||
```python
|
||||
ConversationContext.tags.like(func.concat('%"', tag, '"%'))
|
||||
```
|
||||
|
||||
### 3. Improved FULLTEXT search with proper parameterization
|
||||
**File:** `api/services/conversation_context_service.py`
|
||||
**Lines:** 178-201
|
||||
|
||||
**Fixed Code:**
|
||||
```python
|
||||
try:
|
||||
fulltext_condition = text(
|
||||
"MATCH(title, dense_summary) AGAINST(:search_term IN NATURAL LANGUAGE MODE)"
|
||||
).bindparams(search_term=search_term)
|
||||
|
||||
# Secure LIKE fallback using func.concat to prevent SQL injection
|
||||
like_condition = or_(
|
||||
ConversationContext.title.like(func.concat('%', search_term, '%')),
|
||||
ConversationContext.dense_summary.like(func.concat('%', search_term, '%'))
|
||||
)
|
||||
|
||||
# Try full-text first, with LIKE fallback
|
||||
query = query.filter(or_(fulltext_condition, like_condition))
|
||||
except Exception:
|
||||
# Fallback to secure LIKE-only search if FULLTEXT fails
|
||||
like_condition = or_(
|
||||
ConversationContext.title.like(func.concat('%', search_term, '%')),
|
||||
ConversationContext.dense_summary.like(func.concat('%', search_term, '%'))
|
||||
)
|
||||
query = query.filter(like_condition)
|
||||
```
|
||||
|
||||
### 4. Input Validation Added
|
||||
**File:** `api/routers/conversation_contexts.py`
|
||||
**Lines:** 79-90
|
||||
|
||||
**Added:**
|
||||
- Pattern validation for search_term: `r'^[a-zA-Z0-9\s\-_.,!?()]+$'`
|
||||
- Max length: 200 characters
|
||||
- Max tags: 20 items
|
||||
- Tag format validation (alphanumeric, hyphens, underscores only)
|
||||
|
||||
```python
|
||||
search_term: Optional[str] = Query(
|
||||
None,
|
||||
max_length=200,
|
||||
pattern=r'^[a-zA-Z0-9\s\-_.,!?()]+$',
|
||||
description="Full-text search term (alphanumeric, spaces, and basic punctuation only)"
|
||||
)
|
||||
```
|
||||
|
||||
```python
|
||||
# Validate tags to prevent SQL injection
|
||||
if tags:
|
||||
import re
|
||||
tag_pattern = re.compile(r'^[a-zA-Z0-9\-_]+$')
|
||||
for tag in tags:
|
||||
if not tag_pattern.match(tag):
|
||||
raise HTTPException(
|
||||
status_code=status.HTTP_400_BAD_REQUEST,
|
||||
detail=f"Invalid tag format: '{tag}'. Tags must be alphanumeric with hyphens or underscores only."
|
||||
)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Files Modified
|
||||
|
||||
1. `D:\ClaudeTools\api\services\conversation_context_service.py`
|
||||
- Added `func` import from SQLAlchemy
|
||||
- Fixed all LIKE clauses to use `func.concat()` instead of f-strings
|
||||
- Added try/except for FULLTEXT fallback
|
||||
|
||||
2. `D:\ClaudeTools\api\routers\conversation_contexts.py`
|
||||
- Added pattern validation for `search_term`
|
||||
- Added max_length and max_items constraints
|
||||
- Added runtime tag validation
|
||||
|
||||
3. `D:\ClaudeTools\test_sql_injection_security.py` (NEW)
|
||||
- Comprehensive test suite for SQL injection attacks
|
||||
- 20 test cases covering various attack vectors
|
||||
|
||||
4. `D:\ClaudeTools\test_sql_injection_simple.sh` (NEW)

|
||||
|
||||

|
||||
|
||||
## Security Improvements
|
||||
|
||||
### Defense in Depth
|
||||
|
||||
**Layer 1: Input Validation (Router)**
|
||||
- Regex pattern matching
|
||||
- Length limits
|
||||
- Character whitelisting
|
||||
|
||||
**Layer 2: Parameterized Queries (Service)**
|
||||
- SQLAlchemy `func.concat()` for dynamic LIKE patterns
|
||||
- Parameterized `text()` queries with `.bindparams()`
|
||||
- No string interpolation in SQL
|
||||
|
||||
**Layer 3: Database**
|
||||
- FULLTEXT indexes already applied
|
||||
- MariaDB 10.6 with proper escaping
|
||||
|
||||
---
|
||||
|
||||
## Attack Vectors Mitigated
|
||||
|
||||
1. **Basic SQL Injection**: `' OR '1'='1`
|
||||
- Status: BLOCKED by pattern validation (rejects single quotes)
|
||||
|
||||
2. **UNION Attack**: `' UNION SELECT * FROM users--`
|
||||
- Status: BLOCKED by pattern validation
|
||||
|
||||
3. **Comment Injection**: `test' --`
|
||||
- Status: BLOCKED by pattern validation
|
||||
|
||||
4. **Stacked Queries**: `test'; DROP TABLE contexts;--`
|
||||
- Status: BLOCKED by pattern validation (rejects semicolons)
|
||||
|
||||
5. **Time-Based Blind**: `' AND SLEEP(5)--`
|
||||
- Status: BLOCKED by pattern validation
|
||||
|
||||
6. **Tag Injection**: Various malicious tags
|
||||
- Status: BLOCKED by tag format validation
|
||||

|
||||
- 20 comprehensive tests
|
||||
- Tests both attack prevention and valid input acceptance
|
||||
- Requires unittest (no pytest dependency)
|
||||
|
||||
**Bash Test Script:** `test_sql_injection_simple.sh`
|
||||
- 12 essential security tests
|
||||
- Simple curl-based testing
|
||||
- Color-coded pass/fail output
|
||||
|
||||
### To Run Tests
|
||||
|
||||
```bash
|
||||
# Python test suite
|
||||
python test_sql_injection_security.py
|
||||
|
||||
# Bash test script
|
||||
bash test_sql_injection_simple.sh
|
||||
```
|
||||

|
||||
|
||||
## Deployment Required
|
||||
|
||||
The fixes are complete in the code, but need to be deployed to the running API server.
|
||||
|
||||
### Deployment Steps
|
||||
|
||||
1. **Stop Current API** (on RMM server 172.16.3.30)
|
||||
2. **Copy Updated Files** to RMM server
|
||||
3. **Restart API** with new code
|
||||
4. **Run Security Tests** to verify
|
||||
|
||||
### Files to Deploy
|
||||
|
||||
```
|
||||
api/services/conversation_context_service.py
|
||||
api/routers/conversation_contexts.py
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Verification Checklist
|
||||
|
||||
After deployment, verify:
|
||||
|
||||
- [ ] API starts without errors
|
||||
- [ ] Valid inputs work (HTTP 200)
|
||||
- [ ] SQL injection attempts rejected (HTTP 422/400)
|
||||
- [ ] Database functionality intact
|
||||
- [ ] FULLTEXT search still operational
|
||||
- [ ] No performance degradation
|
||||

## Security Audit
|
||||
|
||||
**Before Fixes:**
|
||||
- SQL injection possible via search_term parameter
|
||||
- SQL injection possible via tags parameter
|
||||
- No input validation
|
||||
- Vulnerable to data exfiltration and manipulation
|
||||
|
||||
**After Fixes:**
|
||||
- All SQL injection vectors blocked
|
||||
- Multi-layer defense (validation + parameterization)
|
||||
- Whitelist-based input validation
|
||||
- Production-ready security posture
|
||||
|
||||
**Risk Level:**
|
||||
- Before: CRITICAL (9.8/10 CVSS)
|
||||
- After: LOW (secure against known SQL injection attacks)
|
||||
