Joomla Extension - regularlabs.com - Privileged stored XSS via link option in Articles Anywhere extension for Joomla < 20.0.0 - Articles Anywhere accepts link options such as onclick and onmouseover. In affected versions, those options become real HTML event attributes without checking the article author's trust level. The plugin syntax survives Joomla's normal Author content filter because the executable HTML is generated later.
