• Scan requests can be initiated without verification
• No rate limiting on scan initiation
• No API key validation

Required Implementations:

# Add to base_scanner.py
class BaseScanner:
    def __init__(self, scan_id, target, domain, auth_headers=None, 
                 api_key=None, user_id=None, **kwargs):
        self.api_key = api_key
        self.user_id = user_id
        self._validate_api_key()
    
    def _validate_api_key(self):
        """Validate API key against database or auth service"""
        if not self.api_key:
            raise SecurityException("API key required")
        # Implement JWT or API key validation

Recommendations:

• Implement JWT-based authentication for scan requests

Required Implementations:

# Add to base_scanner.py
import ipaddress
from urllib.parse import urlparse

class BaseScanner:
    def _validate_target(self, target):
        """Prevent SSRF attacks"""
        parsed = urlparse(target)
        
        # Block internal IP ranges
        try:
            ip = ipaddress.ip_address(parsed.hostname)
            if ip.is_private or ip.is_loopback or ip.is_link_local:
                raise SecurityException("Internal IP addresses not allowed")
        except ValueError:
            pass
        
        # Block localhost variants
        blocked_hosts = ['localhost', '127.0.0.1', '0.0.0.0', 
                        '169.254.169.254', 'metadata.google.internal']

            raise SecurityException("Blocked hostname")
        
        # Block file:// and other dangerous schemes
        if parsed.scheme in ['file', 'ftp', 'gopher', 'dict']:
