Recommendation: Plan a near-term fix — a public PoC already exists.

Quick.CMS 6.7 contains a cross-site scripting vulnerability in the sliders form that allows authenticated attackers to inject malicious scripts by submitting XSS payloads through the sDescription parameter. Attackers can craft CSRF forms targeting the admin.php?p=sliders-form endpoint to execute arbitrary JavaScript in victim browsers when the form is submitted.
