CVE-2026-65882Network attack vector

Reflected XSS via unescaped wrapper goto parameter

Published Jul 28, 2026 · Updated Jul 28, 2026

Reflected XSS in Joomdle before 3.1.1 allows remote attackers to run script in a user's browser through a crafted goto URL. The Moodle wrapper endpoint reflects the goto URL parameter into its response without neutralizing script-capable input for the page context. Exploitation requires a user to open an attacker-controlled wrapper URL, enabling browser-context data access or actions as that user.
