## Technical details

This is a cross-site request forgery (CSRF) vulnerability in FluentBooking Pro versions up to 2.2.4 that lacks proper CSRF token validation. The vulnerability is unauthenticated in the sense that no attacker credentials are required; however, successful exploitation requires a privileged user (logged-in administrator) to be tricked into visiting a malicious page or clicking a crafted link that triggers unintended actions via forged requests. The attack vector is network-based and requires user interaction. The plugin was patched in version 2.2.5, which introduces proper CSRF protections.
