Response Tampering

An entitlement check runs client-side against a verdict the server already sent. Rewrite the verdict on its way back and unlock the gated resource.

Premium report

This resource is entitlement-gated. Click below to check your access. The verdict is decided by the server and re-checked in your browser — intercept the response with a proxy and rewrite the verdict before it reaches the page.

This is an isolated, intentionally-vulnerable sandbox. Data here is fake and scoped to you. The rest of CSPSHIVAM Playground is not part of the target.
