System Documentation

What problem does it solve?

This Skill helps reviewers find prototype pollution weaknesses in JavaScript and Node.js applications before attacker-controlled object paths can alter behavior, authorization, or runtime state.

Core Features & Use Cases

  • Risk Tracing: Follows untrusted data through object creation, deep merge logic, clone utilities, and property assignment paths.
  • Security Review Guidance: Checks for dangerous keys, inherited property abuse, and missing hardening controls such as null-prototype objects or runtime mitigations.
  • Use Case: Review a Node.js service that parses JSON or query parameters and determine whether crafted input could poison shared prototypes and affect later requests.

Quick Start

Ask the skill to review the selected codebase for prototype pollution risks in object creation, deep merges, and property assignment paths.
