At a glance

CVE-2026-2931 is a high-severity Improper Privilege Management vulnerability in the Booking for Appointments and Events Calendar WordPress plugin, affecting versions 8.3 – 9.1.2. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Customer level or above. The issue is fixed in version 9.2; sites on affected versions should update now. Disclosed March 2026, reported by Hunter Jensen (skid).

Vulnerability Overview

The Amelia Booking plugin for WordPress is vulnerable to Insecure Direct Object References in versions 8.3 to 9.1.2. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with customer-level permissions or above to change user passwords and potentially take over administrator accounts. The vulnerability is in the pro plugin, which has the same slug.

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 8.3 – 9.1.2 takes an account at Customer 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 9.2: builds 8.3 – 9.1.2 are affected, anything from 9.2 onward is not.

Remediation

Update to version 9.2, 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 9.2 closes this, and updating the plugin is the step that ends it.
