Skill UI

A specialized security testing skill designed to identify excessive data exposure in REST or GraphQL APIs, adhering to OWASP API3:2023 guidelines. It works by intercepting raw API responses and systematically comparing the returned data against what the frontend UI actually displays. This helps auditors detect leaked PII, internal identifiers, debug fields, or other sensitive business data that should have been filtered out by the endpoint response. Use cases include auditing microservice boundaries, assessing mobile API responses designed for multiple clients, and verifying proper respons...

This script automates the testing of API endpoints for mass assignment (over-posting) vulnerabilities, adhering to OWASP API3:2023 guidelines. It systematically injects undocumented, privileged fields (like 'role', 'isAdmin', 'balance', 'price') into request bodies of typical endpoints (e.g., profile updates, order creation). It checks if the server binds these unexpected fields to the data model without proper filtering, potentially allowing unauthorized privilege escalation or data manipulation.
