CVE-2026-102426: Joomla Extension - joomshaper.com - Reflected XSS in the Dynamic Content Filter addon in SP Page Builder Pro 3.0.0 - 5.6.1p2
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 dcfilter<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 dcfilter<fieldId> value.

No. An unauthenticated attacker can supply a crafted dc_filter_<fieldId> request parameter and cause arbitrary HTML or JavaScript to be reflected in the rendered page.
What request format is needed to trigger the issue?
The affected value is supplied through a dc_filter_<fieldId> parameter. The application splits the value using the l-r delimiter, and the resulting minimum or maximum value is rendered as unescaped span text.
