Security audit

React Flow

Security checks for vulnerabilities and agentic risk

Overview

This skill is documentation for using React Flow and does not show hidden, destructive, or credential-seeking behavior.

Install this as normal React Flow guidance. Be aware that copying the optional viewport persistence example will store viewport position and zoom in the browser across sessions; use that pattern only when persistent UI state is desired.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding
This markdown file includes an example that persists viewport data via localStorage, which affects user data by storing state across sessions. The surrounding documentation presents this as an optional action but does not warn that it writes persistent data in the browser.
