Published

Joomla Extension - regularlabs.com - Privileged stored XSS via event handler option in Modals Pro extension for Joomla < 17.0.0 - Modals Pro intentionally supports JavaScript Events such as on-open and on-closed. Affected versions do not distinguish trusted extension configuration from event code supplied in ordinary article content. A lower-privileged author can therefore use a documented executable feature which should be reserved for trusted authors.
