CVE-2026-11398: CWE-862 Missing Authorization in latepoint LatePoint – Calendar Booking Plugin for Appointments and Events
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.
AI Analysis
Technical Summary
CVE-2026-11398 is an authorization bypass vulnerability (CWE-862) in the LatePoint WordPress plugin for calendar booking and appointments. Versions up to 5.6.1 do not properly verify user authorization when processing booking form submissions, specifically in the process_step_customer() function when guest bookings are enabled (is_customer_auth_disabled() returns true). This allows unauthenticated attackers to modify sensitive customer data such as first name, last name, phone number, and notes by submitting the booking form with a known customer's email address, including records linked to administrator accounts.
Potential Impact
An attacker can modify personally identifiable information of any existing customer record without authentication, potentially impacting data integrity and privacy. There is no direct confidentiality or availability impact reported. The vulnerability requires guest bookings to be enabled to be exploitable.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to disable guest bookings (which enables the vulnerable unauthenticated code path) to prevent exploitation. Monitor vendor channels for official patches or updates addressing this vulnerability.
