Technical details

The VikBooking Hotel Booking Engine & PMS plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability due to insufficient input sanitization and output escaping on the 'vbfX' parameter. The root cause is located in the public-facing 'saveorder' task, which fails to enforce authentication or capability checks. An unauthenticated remote attacker can submit a malicious payload via a crafted request to the booking engine. This payload is stored in the database and executed in the context of any user (including administrators) who views the compromised booking record in the management interface. The vulnerability is addressed in versions following 1.8.13.
