Mass Assignment Scanner
Detects mass assignment vulnerabilities allowing modification of protected attributes.
What is Mass Assignment?
Mass assignment occurs when applications automatically bind request parameters to object properties without filtering. Attackers can inject unexpected parameters (like isAdmin=true or balance=999999) to modify protected attributes they shouldn't have access to.
Why is This Important?
Mass assignment can escalate privileges, modify financial balances, bypass access controls, and manipulate any attribute that the application blindly accepts from requests. It's common in frameworks with automatic model binding.
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.

Frequently Asked Questions
Which frameworks are commonly vulnerable?
Ruby on Rails (strong_parameters needed), Spring (model binding), Node.js ORMs (Mongoose, Sequelize), Laravel (without $fillable/$guarded), and any framework with automatic binding.
What parameters do attackers try?
Role/permission fields (isAdmin, role), account balance, verification status, internal IDs, creation/update timestamps, and any sensitive attributes in the data model.
How do I find vulnerable parameters?
Study the data model for sensitive attributes, check API responses for hidden fields, try common parameter names like 'admin', 'role', 'verified', and 'balance'.
How do I prevent mass assignment?
Explicitly whitelist allowed parameters (strong params in Rails, $fillable in Laravel), use DTOs/ViewModels, and never bind directly to domain objects.
