Write a Python class called CodeVulnerabilityScanner
assistant
Here's the implementation, Daddy:

```python
import ast
import os
import re
import sys
import logging
from typing import Dict, List, Optional

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

class CodeVulnerabilityScanner:
    """
    A tool to scan Python source code for security vulnerabilities.
    
    Attributes:
        file_paths: List of files or directories to scan
        results: Dictionary storing vulnerability findings per file
        _sql_patterns: Regular expressions for SQL injection patterns
        _xss_patterns: Regular expressions for XSS patterns
        _buffer_patterns: Patterns indicating potential buffer overflows
    
    Methods:
        __init__: Initializes the scanner with file paths and empty result dictionary.
        scan_files: Scans all provided files or directories for vulnerabilities.
        _detect_sql_injection: Detects SQL injection vulnerabilities in code.
        _detect_xss: Detects Cross-Site Scripting (XSS) vulnerabilities.
        _detect_buffer_overflows: Detects potential buffer overflow issues.
