Official description

The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'guests[][][documents]' Parameter in all versions up to, and including, 1.8.17 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. This requires the attacker to possess a valid booking sid/ts pair, which can be obtained by making a standard public booking, as the session token needed to satisfy the JSession::checkToken() gate is emitted in the publicly accessible pre-checkin form.
