Joomla Extension - regularlabs.com - Reflected XSS in Articles Anywhere extension for Joomla < 20.0.0, Users Anywhere extension for Joomla < 2.1.0 - Articles Anywhere Pro and Users Anywhere Pro return values from request-input data tags without making them safe for the context in which the tag is used.

A visitor-controlled request value can therefore become an executable URL or a new event attribute in output configured by a site author.
