Summary

The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 5.6.9 via the set_customer_object due to missing validation on a user controlled key. This allows unauthenticated attackers to enumerate arbitrary customer records and disclose personally identifiable information - including first name, last name, email address, and phone number - by iterating the customer[id] parameter. This issue is exploitable only when the site is configured with customer authentication disabled (guest checkout enabled).

Risk Assessment

Exposure of customer PII can violate privacy and lead to GDPR or other regulatory breaches, as well as phishing attacks against customers.

Recommendation

Update the plugin to a patched version. If not available, disable guest checkout or implement additional authorization mechanisms.
