**Name of the Vulnerable Software and Affected Versions**
LatePoint – Calendar Booking Plugin for Appointments and Events versions prior to 5.6.4
**Description**
An Insecure Direct Object Reference (IDOR) exists in the `LatePointAbilityDeleteBooking::execute` function due to missing validation on a user-controlled key. Attackers with LatePoint Agent-level access or higher can read bookings and customer personally identifiable information (PII), including full names, emails, phone numbers, and notes assigned to other agents. Additionally, they can delete arbitrary bookings by providing any booking ID. This issue is only exploitable if an administrator has enabled the Abilities API toggles `latepoint abilities api`, `latepoint abilities api delete`, and/or `latepoint abilities api edit` in the plugin settings.
**Recommendations**
Update the plugin to version 5.6.4 or later.
Disable the `latepoint abilities api`, `latepoint abilities api delete`, and `latepoint abilities api edit` toggles in the plugin settings as a temporary mitigation.
