LatePoint <= 5.1.94 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode

The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' parameter of the 'latepoint_resources' shortcode in all versions up to, and including, 5.1.94 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
