## Overview

The TopBar plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.0. This is due to missing or incorrect nonce validation on the fme_nb_topbar_save_settings() function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
