Vulnerability Overview

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Reaching this weakness in Booking for Appointments and Events Calendar <= 2.3 takes an account at Subscriber level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Booking for Appointments and Events Calendar the fix is 2.4: builds <= 2.3 are affected, anything from 2.4 onward is not.

Remediation

Update to version 2.4, 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 2.4 closes this, and updating the plugin is the step that ends it.
