    This has to be used to make WP a CSP compliant system (at least, in the front end. Remains to be tested in the admin area)

    function wpdocs_add_nonce_to_scripts( $attr ) {
	if ( 'text/javascript' !== $attr['type'] ) {
		return $attr;
	}

	return array(
		'type' => 'text/javascript',
		'nonce' => '123',// Your Nonce. Obviously more featured than this example.
	);
}
add_filter( 'wp_inline_script_attributes', 'wpdocs_add_nonce_to_scripts' );

    Then, you can use 'nonce-123' in your CSP Policy, example:
    "script-src 'self' 'noncoe-123';"
