Recipe - Injection - SQL Injection in JPA: EntityManager#createNativeQuery

Description:

Documentation

Use parameterized queries to prevent SQL injection.

Dynamically creating queries by means of concatenating (untrusted) user input puts the application at risk of SQL injection. An attacker could insert malicious input to obtain or modify data.

Before
entityManager.createNativeQuery("Select * from Books where author = " + author)
    .getResultList();
After
entityManager.createNativeQuery("Select * from Books where author = ?")
    .setParameter(1, author).getResultList();
