Profile Builder permits Contributor-level stored cross-site scripting
Profile Builder through 4.0.0 insufficiently sanitizes and escapes the date shortcode attribute. When an administrator has enabled wppb_toolbox_shortcodes_settings[format-date], a Contributor or higher can store script that executes when another user views the affected page.

Technical description
The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'date' Shortcode Attribute in all versions up to, and including, 4.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the wppb_toolbox_shortcodes_settings[format-date] option to be set to 'yes' by an administrator for the shortcode to be active and the vulnerability to be exploitable.
