Simon Willison has developed an experimental method to bypass Content Security Policy (CSP) restrictions in web applications. This technique involves running an app within a sandboxed iframe and using a custom fetch function to intercept CSP errors. The parent window can then prompt the user to add the problematic domain to an allow-list, enabling the app to refresh and function correctly. Willison built this demonstration using GPT-5.5 xhigh within the Codex desktop application. AI
