CVE-2026-11398: LatePoint Calendar Booking Plugin authorization bypass in process_step_customer

CVE-2026-11398 · Severity: medium · CVSS 5.3 · Published 2026-07-03

Technical details

A missing authorization vulnerability (CWE-862) exists in the LatePoint WordPress plugin due to insufficient validation in the process_step_customer() function. When guest bookings are enabled (is_customer_auth_disabled() returns true), an unauthenticated attacker can reach a code path that updates customer metadata based on the provided email address. By submitting a booking form with a known customer's email, an attacker can overwrite PII including first name, last name, phone number, and notes for any existing record, including those associated with administrators. The vulnerability is present in all versions up to and including 5.6.1.
