Understanding ExpressJS Security Vulnerabilities:
  • Cross-Site Scripting (XSS): XSS vulnerabilities occur when an attacker injects malicious scripts into a web application, which then gets executed by unsuspecting users. This can lead to unauthorized data access, session hijacking, and more. 

Fix: Implement input validation and output encoding to prevent malicious script injections. Use security libraries and frameworks that offer XSS protection. 

  • SQL Injection: Attackers exploit poorly sanitized user inputs to manipulate SQL queries, potentially gaining unauthorized access to databases and compromising sensitive data. 

Fix: Utilize parameterized queries and prepared statements to prevent SQL injection attacks. Validate and sanitize user inputs before processing them. 

  • Cross-Site Request Forgery (CSRF): CSRF attacks involve tricking authenticated users into performing actions on a web application without their consent. This can lead to unintended changes in user settings or data. 

Fix: Implement CSRF tokens and validate the origin of requests to ensure they come from trusted sources. Additionally, use the Same Site attribute in cookies to restrict cross-origin requests.
