What Is SQL Injection in a CMS?
BeginnerQuick Answer
TL;DR
SQL injection is an attack where a hacker inserts malicious database commands into input fields (search boxes, login forms, URL parameters) on a CMS-powered website. If the CMS doesn't properly validate and sanitize user input, the malicious SQL code executes against the database, potentially exposing all stored content, user credentials, and sensitive data. SQL injection remains one of the OWASP Top 10 web vulnerabilities and is a primary attack vector against traditional CMS platforms.
Key Takeaways
- SQL injection exploits CMS input fields that don't properly sanitize user data before database queries
- It can expose entire databases: content, user accounts, passwords, and configuration data
- WordPress, Drupal, and Joomla plugins are common SQL injection targets due to inconsistent input validation
- Prevention requires parameterized queries (prepared statements), input validation, and least-privilege database access
- Headless CMS platforms using managed APIs are largely immune to traditional SQL injection
