01 · Context & problem
Web Security Challenges
These exercises turn web-security concepts into small applications that students can inspect and reason about. Each challenge focuses on a specific behavior in application code, from input handling to authentication.
02 · What I built
Organized separate exercises for SQL injection, loose PHP comparisons, regular-expression handling and JWT authentication.
Published the PHP and JavaScript sources, page assets and supporting SQL files so the exercises can be inspected.

One concept at a time
Separate challenge directories make it possible to study individual application behaviors.
Source available for discussion
The application code gives students concrete material to inspect when discussing why a vulnerability exists.
Teaching context
These intentionally vulnerable exercises are learning material for a controlled lab environment.
