Summary

Joomla Extension Tabs & Accordions (regularlabs.com) versions < 3.1.0 contains a privileged stored XSS vulnerability via the rtla-alias option. The extension 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.

Risk Assessment

The vulnerability allows a low-privileged author to inject persistent malicious scripts, potentially leading to code execution in other users' browsers. This may result in session theft or account takeover.

Recommendation

Update Tabs & Accordions to version 3.1.0 or later. Until then, restrict content author privileges.
