Common issues and fixes

Missing X-Frame-Options

Without X-Frame-Options, your page can be embedded in iframes and used for clickjacking attacks.

No frame-ancestors in CSP

CSP frame-ancestors restricts embedding. Use 'none' or 'self' for sensitive pages.

X-Frame-Options: ALLOW-FROM deprecated

ALLOW-FROM is not supported in modern browsers. Use CSP frame-ancestors instead.
