Administrator-level stored XSS via unescaped slider name
Published Sep 26, 2022 · Updated May 22, 2025
Stored XSS in QuantumCloud Slider Hero before 8.4.4 allows remote authenticated users to execute script through a slider Name. The slide editor stores the Name without escaping it before placing it in an HTML attribute, so event-handler input becomes executable markup. Administrator privileges are required to save the payload, and the script runs when the affected slide is edited again, enabling actions in that viewer's WordPress session.
