security/csp-meta-ignored
frame-ancestors, report-uri, sandbox and X-Frame-Options are sent as HTTP headers; in a meta tag they do nothing.

Dlaczego
Browsers ignore these settings when they come from a <meta> tag, so the page looks protected in the source but can still be framed by any site (clickjacking) and violations are never reported.
Poprawka
Send Content-Security-Policy (with frame-ancestors 'none' or 'self') and, for old browsers, X-Frame-Options: DENY as response headers from the server or the host's headers file. A meta CSP is fine for the directives it supports (script-src, default-src, object-src, base-uri), placed early in <head>.
