Official description
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'button_caption' parameter in the [latepoint_resources] shortcode in versions up to and including 5.3.0. This is due to insufficient output escaping when the 'items' parameter is set to 'bundles'.
