The OWASP Top 10, Explained for Non-Security Teams

The OWASP Top 10 gets referenced constantly in security discussions, but the official documentation is written for security specialists. Here's the plain-language version.

Broken access control

This means users can access data or actions they shouldn't be able to — like viewing another user's account by simply changing an ID in the URL. It's consistently the most common critical vulnerability found in real applications.

Injection attacks

When user input gets inserted directly into a database query or command without proper handling, attackers can manipulate that input to run their own commands. This is largely preventable with parameterized queries, which most modern frameworks handle by default if used correctly.

Security misconfiguration

Default passwords left unchanged, verbose error messages exposing system details, or unnecessary services left running are surprisingly common findings in security audits — not because of complex attacks, but simple oversight.

Why this list matters for every team

You don't need to be a security specialist to avoid most of these issues. Understanding the categories helps developers write safer code by default and helps business teams ask the right questions before launch.
