Technical details

The plugin fails to sanitize and properly escape user input in the 'guests[][][documents]' parameter during check-in, allowing stored XSS injection. Unauthenticated attackers can inject arbitrary JavaScript by making a public booking and obtaining the JSession token from the pre-checkin form. The injected scripts persist in the database and execute whenever an authorized user accesses the affected booking record.
