CVE-2026-9720
The Facturación Electrónica Costa Rica plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.2. This is due to missing or incorrect nonce validation on the (global scope, included by fvcr_admin_page_html) function. This makes it possible for unauthenticated attackers to modify the plugin's configuration, including API tokens, access tokens, economic activity, Hacienda environment mode, invoice and ticket emission flags, exchange rate, and branch settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
