What is CVE-2026-103366?

The LatePoint Appointment Booking Plugin for WordPress contains a serious security flaw that allows unauthenticated users to exploit Insecure Direct Object Reference. This vulnerability arises from how raw request parameters go unchecked, enabling attackers to guess and enumerate booking and cart identifiers. Consequently, sensitive appointment details, including service names, times, and pricing information, may be exposed, leading to privacy violations and unauthorized data access for other users' bookings and shopping carts.

Affected Version(s)
