The exam also tightened: you must now exploit a fully patched, custom web application with no known CVEs – only logic and implementation flaws.
The WEB-300 course was recently updated to include modern vulnerability classes:
1. Type Juggling & Loose Comparisons (PHP)
- Exploiting
== vs === in PHP’s loose comparison engine.
- Using magic hashes (
0e12345 matching 0e67890).
- Real-world impact: Bypassing authentication or OTP checks.
course, remains a premier white-box web security credential. As of early 2026, the course material has been updated with expanded challenge labs and modern vulnerability modules.
