Description
Joomla Extension - regularlabs.com - Privileged stored XSS via data-rlta-url attributes in Tabs & Accordions (Pro) 2.3.0 - 3.1.0 - Tabs & Accordions Pro accepts a url option for an item and writes it to a generated data-rlta-url attribute. The browser code passes that value to window.open() when the item is activated. Affected versions do not reject browser URL schemes which execute JavaScript. Joomla sees ordinary plugin syntax while filtering the authored article; Tabs & Accordions creates the executable browser behavior later while rendering the article.
