CVE-2024-13821: WP Booking Calendar <= 10.10 - Unauthenticated Post-Confirmation Booking Manipulation

Q: What type of vulnerability is CVE-2024-13821?

CVE-2024-13821 is an unauthenticated post-confirmation booking manipulation vulnerability.

First published: Wed Feb 12 2025(Updated: )

The WP Booking Calendar plugin for WordPress is vulnerable to Unauthenticated Post-Confirmation Booking Manipulation in all versions up to, and including, 10.10. This is due to the plugin not properly requiring re-verification after a booking has been made and a change is being attempted. This makes it possible for unauthenticated attackers to manipulate their confirmed bookings, even after they have been approved.
