 "title": "VikBooking Hotel Booking Engine & PMS <= 1.8.17 - Unauthenticated Sensitive Information Exposure via U-tec Webhook Debug Log",
 "description": "The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Sensitive Information Exposure via the U-tec door access webhook endpoint in versions 1.8.7 up to, and including, 1.8.17, due to the U-tec webhook handler writing the raw request body, request parameters and server variables to a webhook_debug.txt file inside the plugin directory, where the web server can serve it. The public apps.webhook endpoint also accepted any door access profile ID for the U-tec provider. This makes it possible for unauthenticated attackers to read the logged webhook data, including requests that U-tec sent to the site, and server environment details from that file, provided at least one door access control profile is configured.",
