Stored script execution via unescaped shortcode attribute
Published May 7, 2025 · Updated Apr 28, 2026
Stored XSS in Beds24 Online Booking 2.0.29 and earlier allows remote authenticated users to execute scripts via shortcode attributes. The plugin outputs an attacker-controlled shortcode attribute without escaping, causing the payload to persist in generated page content. Low-privileged WordPress access is required to save the shortcode, and another user's page visit runs the stored script in that user's browser.
