Player: @g00siferdev-py
Achievement: Root Access & Fixed All Vulns

I completed the full exploit chain against the intentionally vulnerable application and then patched all identified vulnerabilities in my fork.

Exploit chain demonstrated

1. Mass assignment / privilege escalation — PATCH /profile with role: Chef
2. OS command injection — /admin/stats/disk?parameters=;whoami
3. IDOR — GET /orders/{other_user_order_id}
4. Information disclosure — unauthenticated GET /debug
5. JWT algorithm confusion / none attack
6. Weak password reset PIN brute force
7. IP-spoofable admin password reset
8. Hardcoded fallback database password
