Description
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'booking_form_page_url' parameter in all versions up to, and including, 5.5.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The malicious activity log entry is written to the database even when Stripe is not configured, because the latepoint_order_intent_created action hook fires before the Stripe Connect account ID is validated, meaning a fully functional Stripe integration is not required for exploitation.
Problem types
