What the vulnerability does
01Description
The Games Catalog plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.0. This is due to missing or incorrect nonce validation on the gc_crud() function which handles the delete action (action=delete) via a GET request without any wp_verify_nonce() / check_admin_referer() call. This makes it possible for unauthenticated attackers to delete arbitrary game catalog entries (including the associated WordPress post created for the game) via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the Games Catalog without the admin's knowledge. The vulnerability requires the victim to visit the attacker's page while authenticated.
