Clickjacking is one of those “everything works” security problems that teams ignore because nothing crashes, nothing burns, and monitoring stays green. And that’s exactly why it survives.
Your API can be flawless, your backend locked down — but if your UI can be framed, a user can be tricked into clicking real actions through someone else’s page. Approvals, settings, payments, permissions. All valid. All invisible.
Rentgen checks the boring stuff people forget: X-Frame-Options and CSP frame-ancestors. If they’re missing, the page can be embedded. No exploit magic. Just a quiet risk waiting for the wrong moment.
This isn’t a “bug”. It’s worse. It’s a security gap that only shows up when real users are involved — which is usually too late.
