Brizy - Page Builder < 1.0.114 - Unauthenticated Site Settings Update

Edit (WPscanTeam)

The plugin fails to restrict access to the site settings page, allowing unauthenticated users to change them, such as site title, description as well as put XSS payload in the footer, leading to Unauthenticated Stored XSS issues.

As we saw probes in the wild checking for the issue, we choose to disclose it (see below for details).

February 10th, 2020 - Report received & WP Plugins Team notified.
February 12th, 2020 - WP Plugin Team Investigating

Proof of Concept
Access []/wp-content/plugins/brizy/admin/site-settings.php
