Preventing SQL injection: a Django author's perspective

SQL Injection (SQLi) is a severe web vulnerability that occurs when user inputs are improperly included in SQL queries, potentially leading to data breaches or database damage. While frameworks like Django's ORM mitigate many SQLi risks by using parameterized statements, developers must remain vigilant, especially when using raw SQL queries or custom ORM additions. Effective prevention involves never trusting user data, consistently using parameterized queries, and employing code analysis tools like Bento, which can detect and prevent SQLi patterns throughout the development process. Although Django's ORM offers robust protection, cautious auditing of custom and third-party code is essential to maintain security, as SQLi vulnerabilities, though rare, can have devastating consequences.
