Missing X-Frame-Options & CSP
Without frame restriction headers, malicious third parties can embed your application in transparent iframes to intercept user clicks.
ALLOW-FROM Obsolete
`X-Frame-Options: ALLOW-FROM` is deprecated across Chromium and WebKit. Use `Content-Security-Policy: frame-ancestors <domain>` instead.
Recommended remediation
Add `Content-Security-Policy: frame-ancestors 'self'` or `X-Frame-Options: SAMEORIGIN` to all authenticated web pages.
