What the vulnerability does

01Description

The WooCommerce Checkout & Funnel Builder by CartFlows plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.15. This is due to missing or incorrect nonce validation on the export_json, import_json, and status_logs_file functions. This makes it possible for unauthenticated attackers to import/export settings and trigger logs showing via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
