Description
Joomla Extension - regularlabs.com - Privileged stored XSS via executable URL schemes in Modals extension for Joomla < 17.0.0 - Modals treats a destination using an executable browser URL scheme as an ordinary modal URL. The value can reach both the generated link and the iframe-loading path. Authored content can consequently become JavaScript in a visitor's browser without using Modals' separate Pro JavaScript Events feature.
