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

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

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 file paths to scan
        results: Dictionary storing vulnerability findings per file
        patterns: Regular expression patterns for different vulnerabilities

    Methods:
        __init__(self, file_paths: List[str])
            Initializes the scanner with list of files to analyze
        
        _scan_file(self, file_path: str) -> Optional[Dict]:
            Scans a single file for vulnerabilities and returns findings
            
        is_sql_injection_prone(self, code_snippet: str) -> bool:
            Checks if SQL injection can occur in given code snippet
            
        is_xss_prone(self, code_snippet: str) -> bool:
            Checks if XSS vulnerability exists in the code snippet
            
        _check_buffer_overflows(self, func_node: ast.FunctionDef, variables: Dict[str, ast.Name]) -> Optional[Dict[str, List[Tuple[int, str]]]]:
            Detects potential buffer overflow issues
        
        is_vulnerable(self, node: ast.AST) -> bool:
            Checks if a given AST node represents a vulnerability
            
        scan(self) -> None:
            Executes the full scan on all files

    Example Usage:
        scanner = CodeVulnerabilityScanner(['app.py', 'models.py'])
        scanner.scan()
        print(scanner.results)
    """

    def __init__(self, file_paths: List[str]):
        """
        Initializes the code vulnerability scanner.

        Args:
            file_paths: List of Python source files to analyze
        """
        self._file_paths = file_paths
        self.results = {}
        self.patterns = {
            'sql_injection': re.compile(r"[cj] \(.*?\)"),
            'xss': re.compile(r"print\(.*?\)"),
        }

    def _scan_file(self, file_path: str) -> Optional[Dict]:
        """
        Scans a single file for vulnerabilities.

        Args:
            file_path: Path to the Python source file

        Returns:
            Dictionary of vulnerability findings or None if no issues found
        """
        try:
            with open(file_path, 'r', encoding='utf-8') as f:
                code = f.read()
            
            tree = ast.parse(code)
            parser = self
```
