Walks through detecting OWASP API3:2023 Broken Object Property Level Authorization flaws, covering excessive data exposure and mass assignment verification with API tests and scripted automation tailored for penetration testers.

Guide for discovering and exploiting mass assignment flaws in REST APIs, covering workflow from field discovery to automated attacks aimed at privilege escalation, financial tampering, and authorization bypass during API security assessments.

Implements API schema validation using OpenAPI/JSON Schema to enforce request and response contracts, block injections, eliminate mass assignment, and prevent data leakage across gateways and CI/CD pipelines.

Automates mass-assignment checks by injecting privileged properties (role, balance, pricing, permissions) into writable JSON/XML API endpoints so security teams can verify OWASP API3 Broken Object Property Level Authorization defenses and spot auto-binding vulnerabilities.
