Vulnerability Overview

The Amelia WordPress plugin before 1.0.48 does not have proper authorisation when handling Amelia SMS service, allowing any customer to send paid test SMS notification as well as retrieve sensitive information about the admin, such as the email, account balance and payment history. A malicious actor can abuse this vulnerability to drain out the account balance by keep sending SMS notification.

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-863: Incorrect Authorization

Reaching this weakness in Booking for Appointments and Events Calendar < 1.0.48 takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For Booking for Appointments and Events Calendar the fix is 1.0.48: builds < 1.0.48 are affected, anything from 1.0.48 onward is not.

Remediation

Update to version 1.0.48, 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 1.0.48 closes this, and updating the plugin is the step that ends it.
