Stored XSS via unescaped shortcode class attribute
Published Jan 9, 2023 · Updated Apr 9, 2025
Stored XSS in Avirtum Vision Interactive 1.5.3 and earlier allows remote authenticated users to execute scripts via a crafted shortcode. The shortcode handler places its class attribute into rendered image markup without sanitizing or escaping attacker-controlled content. Contributor access is sufficient, and the script runs in a visitor's browser when the injected page is viewed or the image is hovered.
