CVE-2026-11398
MediumCVSS 5.3Summary
The LatePoint plugin for WordPress, up to version 5.6.1, has an authorization bypass vulnerability. Unauthenticated attackers can modify personally identifiable information (first name, last name, phone number, and notes) of any existing customer record, including administrator accounts, by submitting the booking form with a known email address. Exploitation requires guest bookings to be enabled.
Risk Assessment
The risk involves potential identity theft or data manipulation of customers and administrators, leading to privacy breaches, fraud, or privilege escalation within the WordPress system.
Recommendation
Immediately update the LatePoint plugin to the latest available version. If an update is not possible, temporarily disable guest bookings in the plugin settings.
Original NVD description (English source)
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.6.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to modify the personally identifiable information (first name, last name, phone number, and notes) of any existing customer record, including those linked to administrator accounts, by submitting the booking form with a known customer's email address. Exploitation requires the plugin to be configured with guest bookings enabled (is_customer_auth_disabled() returning true), which is necessary for the vulnerable unauthenticated code path in process_step_customer() to be reached.
