CVE-2026-85191 Details
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.
A privileged stored cross-site scripting vulnerability has been identified in the Tabs & Accordions extension for Joomla, affecting versions prior to 3.1.0. The issue arises in the rtla-alias option, where the extension rewrites links to match item aliases. The vulnerable renderer improperly sanitizes the alias before inserting it into an HTML onclick attribute as a quoted JavaScript argument. This flaw allows a crafted data-rlta-alias value to manipulate the generated JavaScript handler, leading to cross-site scripting.
