Our team is updating an older enterprise application and we discovered multiple raw database queries. To avoid major vulnerabilities, what are the best practices to prevent how do SQL injection attacks happen? Are Object-Relational Mapping tools completely safe from these exploits?

The primary defense against SQLi is the separation of data from code. Utilizing prepared statements with parameterized queries ensures that the database driver treats user inputs strictly as literal values rather than executable SQL commands. While Object-Relational Mapping frameworks like Hibernate or Entity Framework provide built-in protections by using parameterization automatically, they are not entirely foolproof. If developers bypass the standard ORM APIs to write custom, concatenated native SQL strings inside the application code, the vulnerability is reintroduced.
Are you currently utilizing automated static application security testing tools in your CI/CD pipeline to catch these raw database query vulnerabilities before they reach production?
Using parameterized queries is the absolute gold standard because it completely strips the inputs of any executable power.
Completely agree, Ronald. Additionally, implementing input validation whitelisting and enforcing the principle of least privilege on the database user account provides an excellent defense-in-depth layer.
We are actually looking into integrating SAST tools next month. Right now, we are doing manual code reviews to identify where raw queries are concatenated, but automating this process would definitely help us scale our security efforts much faster.
