Is Node.js Vulnerable to SQL Injection Without Prepared Statements?

Mitigating SQL Injection in Node.js with Escaping and Prepared Statements

Concerns have been raised about the vulnerability of Node.js applications to SQL injections, given that Prepared Statements, a feature that PHP uses to safeguard against such attacks, are not yet implemented in the commonly used node-mysql module.

To address this concern, the node-mysql library employs an automatic escaping mechanism when query values are provided as an object, as demonstrated in the code snippet you provided. This ensures that user input is properly escaped, preventing malicious characters from being executed as part of the query.

If you are using node-mysql in this manner, your application should be protected from SQL injections. However, it's worth noting that raw SQL queries (using execute) or building queries using string concatenation can still pose a risk, as they lack the automatic escaping provided by the connection.query method.

Therefore, switching to node-mysql-native for Prepared Statements is not necessary. However, it's important to be aware of the potential vulnerabilities in other aspects of SQL query handling and to take appropriate precautions.
