## Overview

Joomla Extension - joomshaper.com - Reflected XSS in the Dynamic Content Filter addon in SP Page Builder Pro 3.0.0 - 5.6.1p2 - The slider minimum and maximum values are taken from the dc_filter_<fieldId> request parameter, split on the delimiter "l-r", HTML-escaped inside the data-value attribute, and then echoed without escaping as the span element's text content. An unauthenticated attacker reflects arbitrary HTML or JavaScript into the rendered page through a crafted dc_filter_<fieldId> value.

## Affected

- `sp_page_builder >= 3.0.0, < 5.6.1`
- `sp_page_builder = 5.6.1`

## Remediation

Upgrade past the affected range:

- `sp_page_builder 5.6.1`
