CVE-2026-8418

What is known

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.

Business impact

Successful exploitation of CVE-2026-8418, a medium vulnerability (CVSS 4.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
