Execution After Redirect (EAR)

Free3 Points

Overview

Execution After Redirect (EAR) focuses on an authentication flow where redirect logic does not fully stop protected processing.

This lab covers a subtle access control mistake: sending a redirect response is not the same as terminating the server-side code path.

Security Impact

EAR issues can expose protected data, continue restricted actions, or bypass intended authentication gates. Admin panels, account pages, and restricted flows are especially sensitive when redirect behavior is mistaken for authorization.

Vulnerability Scope

Login checks, middleware, legacy controllers, and custom routing are exposed when code sets a redirect but continues executing protected logic afterward.

Lab Focus

The lab focuses on redirect-based access control, server-side execution order, and why authorization decisions must explicitly stop unauthorized code paths.
