Insecure Frontend Route Guard Lab

Level 1 Client-Side Security simulation: learn why frontend-only route protection is not real authorization.

Beginner

Client-Side Security • 20 min

This lab is a controlled simulation only. No real backend or dangerous code execution is used.

Objective 1

Review a fake dashboard access flow where the UI blocks access based only on frontend role state.

Objective 2

Identify how changing client-side role values can bypass a visual route guard.

Objective 3

Understand why real access control must be enforced by the backend, not just hidden in the UI.

Use the input fields below to safely simulate the vulnerable behavior.

Modified Role / State

Fake Dashboard Access Panel

Current role: user UI state: Access denied (user role) Submitted override: (none yet)

Review the fake route guard and enter a modified role value that bypasses the frontend-only restriction in this simulation.
