Restrict Unfiltered HTML to Administrators
Only administrators may save raw HTML such as scripts and iframes in posts. Editors get the same safe HTML filtering as authors.

Security snippets for WordPress
Snippets that harden WordPress: turn off XML-RPC, hide the version number, stop user enumeration, add security headers and block risky uploads. Small, reviewable changes for site owners who want fewer attack points without a heavy security plugin.
Allow Your Site to Be Embedded Only on Partner Domains
Replaces the usual same-site framing rule with a Content-Security-Policy frame-ancestors list, so your pages can be shown in iframes on the partner sites you name and nowhere else.
Sandbox Iframes From Untrusted Sites in Your Content
Adds a restrictive sandbox to iframes in posts that come from sites not on your trusted list, so an embedded page cannot redirect your visitors, open pop-ups or run scripts against your site.
