# Pre-Release Security Scan Report

**Date**: 2025-11-30
**Scan Type**: Pre-release security assessment
**Release Candidate**: v1.4.0
**Scanned Commits**: origin/main..HEAD

## Executive Summary

**RESULT**: ✅ **CLEAN** - Release approved from security perspective

All changes have been scanned for secrets, credentials, and security vulnerabilities. No production secrets or sensitive credentials detected in tracked files.

## Scan Coverage

### Files Scanned
- ✅ Git diff between origin/main and HEAD (5 files)
- ✅ All environment files (.env, .env.local, .env.example)
- ✅ New documentation files (3 files)
- ✅ Source code changes (2 files)
- ✅ Test files (1 file)
- ✅ Private keys and certificates (.pem, .key)

### Secret Patterns Detected
- API keys (Linear, GitHub, JIRA)
- Tokens and passwords
- Private keys
- Database credentials
- OAuth secrets

## Findings

### 1. Environment Files - INFO ✅

**File**: `.env.local`
**Status**: ✅ **SAFE** (Properly ignored)
**Finding**: Contains Linear API key (masked for security)

**Git Tracking Status**:
```bash
$ git check-ignore -v .env.local
.gitignore:219:.env.*	/Users/masa/Projects/mcp-ticketer/.env.local

$ git ls-files .env.local
# No output - file is NOT tracked

$ git log --all --full-history -- .env.local
# No commits - file never committed
```

**Classification**: **INFO** - This is correct security practice
- ✅ File is properly ignored by .gitignore (line 219: `.env.*`)
- ✅ File is NOT tracked by git
- ✅ File has never been committed to git history
- ✅ No action required

**Justification**: Environment files containing secrets should be gitignored. This is expected behavior and not a security violation.

### 2. Documentation Files - CLEAN ✅

**Files Scanned**:
- `CLAUDE_CLI_IMPLEMENTATION.md` (new)
- `docs/features/claude-code-native-cli.md` (new)
- `docs/research/claude-code-native-mcp-setup-2025-11-30.md` (new)

**Status**: ✅ **CLEAN** - No real secrets found
- All API key references are placeholders (e.g., `your_key`, `xyz`, `***`)
- All examples use masked values for security demonstration
- No production credentials detected

### 3. Source Code Changes - CLEAN ✅

**File**: `src/mcp_ticketer/cli/mcp_configure.py`

**Changes Summary**:
- Added CLI detection function (`is_claude_cli_available()`)
- Added command builder (`build_claude_mcp_command()`)
- Added native CLI configuration (`configure_claude_mcp_native()`)
- Modified main configuration function to use hybrid approach

**Security Features Added**:
- ✅ Credential masking in console output (line 169-189)
- ✅ Environment variable passing (not hardcoded)
- ✅ No secrets in code
- ✅ Secure subprocess handling

**Code Pattern Example**:
```python
# Credentials passed via environment variables, not hardcoded
if "api_key" in linear_config:
    cmd.extend(["--env", f"LINEAR_API_KEY={linear_config['api_key']}"])
```

**Security Assessment**: ✅ SAFE
- Credentials are passed dynamically from configuration
- No hardcoded secrets
- Proper environment variable handling
- Credential masking implemented

### 4. Test Files - CLEAN ✅

**File**: `tests/cli/test_mcp_configure.py`

**Test Credentials Used**:
- `lin_api_test123` - Mock Linear API key (clearly test value)
- `ghp_test123` - Mock GitHub token (clearly test value)
- `lin_api_secret123` - Used for masking tests (clearly test value)

**Security Assessment**: ✅ SAFE
- All credentials are clearly mock/test values
- Test includes verification of credential masking (`assert "lin_api_secret123" not in call_str`)
- No production credentials in tests
- Follows security testing best practices

### 5. .gitignore Validation - COMPLIANT ✅

**Verified Patterns** (all present):
- ✅ `.env` (line 137)
- ✅ `.env.local` (line 138)
- ✅ `.env.*.local` (line 139)
- ✅ `.envrc` (line 140)
- ✅ `*.pem` (line 207)
- ✅ `*.key` (line 201)
- ✅ `*.crt` (line 199)
- ✅ `*.cert` (line 198)
- ✅ `.env.*` (line 219)
- ✅ `.secrets/` (line 225)
- ✅ `credentials/` (line 233)

**Status**: ✅ **COMPREHENSIVE** - All sensitive file patterns properly ignored

### 6. Private Keys and Certificates - CLEAN ✅

**Scan Results**:
- ✅ No `.key` files found in project root or src
- ✅ Only CA certificate bundles found (cacert.pem in venv - expected)
- ✅ No private SSH keys detected
- ✅ No certificate files outside venv

## Security Validation Checklist

- ✅ No API keys in tracked files
- ✅ No passwords in tracked files
- ✅ No tokens in tracked files
- ✅ No private keys in tracked files
- ✅ No database credentials in tracked files
- ✅ Environment files properly gitignored
- ✅ .gitignore contains all sensitive file patterns
- ✅ Test credentials are clearly mock values
- ✅ Documentation uses placeholders only
- ✅ Code passes credentials via environment variables
- ✅ Credential masking implemented for console output

## Attack Vector Assessment

### SQL Injection - N/A
- No database queries in changed code
- No SQL construction patterns detected

### XSS/Code Injection - SECURE ✅
- Subprocess calls use proper list-based arguments (not shell=True)
- No user input directly executed
- Command construction uses parameterized approach

### Path Traversal - SECURE ✅
- File paths validated via `Path()` objects
- No direct string concatenation for paths
- Home directory expansion properly handled

### Command Injection - SECURE ✅
- Subprocess calls use `subprocess.run()` with list arguments
- No shell interpretation enabled
- No unsanitized user input in commands

## Recommendations

### Immediate Actions
**None required** - Release is secure

### Future Enhancements
1. Consider adding pre-commit hook for secret scanning
2. Add automated secret scanning to CI/CD pipeline
3. Consider using git-secrets or similar tools
4. Document credential rotation procedures
