It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Provider level or above.

Vulnerability Overview

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 9.6 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Custom-level access and above, to retrieve arbitrary customer data.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in Booking for Appointments and Events Calendar <= 9.6 takes an account at Provider level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Booking for Appointments and Events Calendar the fix is 9.7: builds <= 9.6 are affected, anything from 9.7 onward is not.

Remediation

Update to version 9.7, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Booking for Appointments and Events Calendar 9.7 closes this, and updating the plugin is the step that ends it.
