Delete Post Revisions In WordPress <= 4.6 - Cross-Site Request Forgery

Description

The delete-post-revisions-on-single-click theme for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.6. This is due to missing or incorrect nonce validation on the create_admin_page() function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
