Page Builder: Pagelayer – Drag and Drop website builder < 1.9.9 - Cross-Site Request Forgery (CSRF) To Post Contents Modification

Description

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.9.8. This is due to missing or incorrect nonce validation on the pagelayer_save_post function. This makes it possible for unauthenticated attackers to modify post contents via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
