This post explains the general difficulty and vulnerability count inside VulnForge.
It does not reveal exact exploit chains, payloads, or step-by-step solutions.

VulnForge: Probably One of the Hardest Damn Local Web Apps To Fully Crack
I wanted a lab that actually fights back instead of falling over after one injection payload. So I built VulnForge. It looks clean on the surface, but the deeper you go into the code, the more you realize this thing is wired to break every rule possible. And not in a simple way. In a layered, modern, annoying, realistic way.
People think vulnerable apps are supposed to be easy. VulnForge is the opposite. If you want something that takes real enumeration, real chaining, and real analysis, this is it. If you want something you can solve in one sitting, this is not it.

When I say this thing is loaded, I mean loaded. Looking at the codebase, VulnForge has more than thirty separate vulnerabilities. And they are spread across every major category.
Here is how bad it gets:
Authentication and session management (8 flaws)
Weak session secrets
Session fixation
JWT hardcoded keys
Username enumeration through timing
No rate limiting
Insecure cookies
Predictable session tokens
No lockout logic
Injection vulnerabilities (6 flaws)
SQL injection
NoSQL injection potential
Command injection in debug routes
LDAP injection
XPath injection
Server side template injection
Access control issues (5 flaws)
IDOR everywhere
Privilege escalation
Missing authorization checks
Path traversal
Leaked admin functions
Cross site scripting (4 flaws)
Stored XSS in messaging
Reflected XSS
DOM XSS
Upload based XSS
File upload vulnerabilities (3 flaws)
Unrestricted uploads
Upload traversal
Executable bypass
API security issues (4 flaws)
Missing API auth
Key exposure
Rate limit bypass
Sensitive data leakage
WebSocket vulnerabilities (2 flaws)
Auth bypass
Admin command execution
Configuration issues (3 flaws)
Debug routes enabled
Sensitive info disclosure
Env variable exposure
Plus bonus problems like CSRF, XXE possibilities, insecure redirects, broken logging, bad crypto choices, and more.
You are not going to solve this thing by accident. You have to enumerate everything. You have to dig into the internal service. You have to analyze the proxy behavior. You have to chain issues together or you will get nowhere.
If you want the full exploit chains, the real attack paths, and the private writeups I made, email me:
If you want a challenge that actually makes you think, try it. It's one of the hardest local web apps you will ever try to fully crack.
