- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- neo2oo5 Neos Connector for Fakturama: through 0.0.14

## Description

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.
