The redeem window also lacks a setWindowOpenHandler restriction, so script injection in sub.wyzie.io, a loaded third-party resource, or a site reached through navigation executes without CSP constraints and can affect additional windows and persistent session storage. A user must open the Wyzie API key redemption window, and exploitation requires attacker-controlled script content in a loaded page.
