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.
