What the vulnerability does
The Coding 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 nonce validation on the settings update functionality. This makes it possible for unauthenticated attackers to update plugin settings including the theme configuration 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
Coding Blocks versions 1.1.0 and earlier contain a cross-site request forgery (CSRF) vulnerability. An attacker can craft a malicious webpage that, when visited by a logged-in user, performs unwanted actions on their behalf. The vulnerability requires user interaction—the victim must visit the attacker's page while authenticated to the Coding Blocks application.
What an attacker can do
Perform actions on behalf of a logged-in user without their knowledge or consent.
Potential impact on your site
Users' accounts can be manipulated to perform unintended actions if they visit malicious links while logged in.
Conditions required to exploit
User must be logged into Coding Blocks and visit an attacker-controlled webpage.
