 This is also relevant for the new website.

 High severity: object-src [missing] Can you restrict object-src to 'none'?

 = What should be done

 - https://content-security-policy.com/#server
 - https://www.w3.org/TR/CSP2/#example-policies
 - ML: https://lists.w3.org/Archives/Public/public-webappsec/

 There's a method to define a [https://www.w3.org/TR/CSP2/#delivery-html-
 meta-element CSP in a meta header] "although in this case its
 effectiveness will be limited"
 ([https://en.wikipedia.org/wiki/Content_Security_Policy#cite_ref-13
 Wikipedia]), for apache it should be defined in {{{httpd.conf}}} or
 {{{.htaccess}}}:
 {{{
 Header set Content-Security-Policy "default-src 'self';"
 }}}
 (just an example, the perfect solution may differ)

 The use of the X-Frame-Options header and Content Security Policy’s frame-
 ancestors directive are a simple and easy way to protect your site against
 clickjacking attacks.
