CVE-2022-4392Public exploitNetwork attack vector

Stored XSS via unescaped shortcode class attribute

Published Jan 9, 2023 · Updated Apr 9, 2025

Stored XSS in Avirtum iPanorama 360 Virtual Tour Builder for WordPress 1.6.29 and earlier allows remote authenticated users to run scripts. The shortcode renderer places the user-controlled class attribute into panorama markup without sanitizing or escaping it, allowing an event-handler attribute to be injected. Contributor-level access and a created panorama are required; the script runs in a viewer's browser when the published panorama is hovered.
