CVE-2026-84166 · Severity: medium · CVSS 4.3 · Published 2026-10-12

The Hotel Booking WordPress plugin is a tool for managing hotel reservations through the WordPress admin interface. Because it lacks CSRF protections, an attacker can trick a logged-in administrator into unknowingly creating, deleting, or modifying booking records by sending them a malicious link or form. This could result in data loss, unauthorized bookings, or disruption of the reservation system.

## Technical details

The plugin lacks CSRF token validation on its administrative booking order management endpoints, allowing attackers to forge requests that execute state-changing operations. An attacker can craft malicious HTML/JavaScript that, when visited by an authenticated admin, performs unwanted actions on booking records. The vulnerability requires admin privileges but no additional user interaction beyond clicking a link or visiting a compromised page.
