WordPress Plugin Vulnerabilities

Visual Form Builder < 3.0.4 - Admin+ Stored Cross-Site Scripting

Description

The plugin does not sanitise or escape its Form Name, allowing high privilege users such as admin to set Cross-Site Scripting payload in them, even when the unfiltered_html capability is disallowed

Proof of Concept

Create a new Form via the plugin, fill it with any values. In the next step, change the Form name to: "/><img src onerror=alert(/XSS/)> and save the form

The XSS will be triggered when viewing the forms list (/wp-admin/admin.php?page=visual-form-builder) or when editing the related form 

Affects Plugins

visual-form-builder
Fixed in version 3.0.6
