Summary
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is affected in all versions up to and including 1.8.17. Insufficient input sanitization and output escaping of the guests[][][documents] parameter lets attackers store scripts (CWE-79). An unauthenticated attacker needs a valid booking sid/ts pair, which a standard public booking provides, and the injected scripts run when a user opens an affected page.

Description from the CNA
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.
