info:
  name: WordPress FluentForms <= 5.1.16 - Broken Access Control
  author: riteshs4hu
  severity: high
  description: |
    The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the /wp-json/fluentform/v1/global-settings REST API endpoint in all versions up to, and including, 5.1.16. This makes it possible for unauthenticated attackers to modify all of the plugin's settings.
