Description
Joomla Extension - regularlabs.com - Privileged stored XSS via rtla-alias option in Tabs & Accordions extension for Joomla < 3.1.0 - Tabs & Accordions rewrites links matching an item alias into calls to its browser API. The affected renderer places the alias inside a quoted JavaScript argument in an HTML onclick attribute without securing both the JavaScript-string and HTML-attribute contexts. A crafted data-rlta-alias value can therefore change the generated handler.
