What the vulnerability does
The Page Blocks plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.0. This is due to missing or incorrect nonce validation on the admin_process_widget_page_change function. This makes it possible for unauthenticated attackers to modify widget page block configurations via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Page Blocks versions 1.1.0 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without the administrator's knowledge or consent. The attacker has no special privileges and the victim must visit the malicious page, but successful exploitation can modify site content or settings.
What an attacker can do
Perform unwanted actions on the site by tricking a logged-in admin into visiting a malicious webpage.
Potential impact on your site
Administrators could unknowingly authorize changes to site content, settings, or data via a crafted link or embedded page.
Conditions required to exploit
Victim must be logged in and visit attacker-controlled webpage; no special privileges required.
