CVE-2026-4143: NEO2OO5 Neos Connector For Fakturama

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

The Neos Connector for Fakturama plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 0.0.14. This is due to missing nonce validation in the ncff_add_plugin_page() function which handles settings updates. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.
