What are the common vulnerabilities in the MEAN stack?

The MEAN stack, which includes MongoDB, Express.js, Angular, and Node.js, has several common vulnerabilities such as SQL injection, NoSQL injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF). Would you like to know more about any specific vulnerability?

Can you explain SQL injection in the context of MEAN stack?

SQL injection is a code injection technique that attackers use to exploit vulnerabilities in an application's software. In the context of the MEAN stack, while MongoDB is a NoSQL database, similar injection attacks can occur if user inputs are not properly sanitized. This can lead to unauthorized access to data.

What about Cross-Site Scripting (XSS)? How does it affect MEAN applications?

Cross-Site Scripting (XSS) occurs when an attacker injects malicious scripts into content that is then served to users. In MEAN applications, if Angular does not properly sanitize user inputs, it can lead to XSS vulnerabilities, allowing attackers to execute scripts in the context of the user's session.

How can I protect my MEAN stack application from these vulnerabilities?

To protect your MEAN stack application, you should implement input validation, use parameterized queries, sanitize user inputs, and employ security libraries like Helmet for Express.js. Regular security audits and keeping dependencies updated are also crucial.
