At a glance

CVE-2026-9232 is a medium-severity Missing Authorization vulnerability in the Easy Appointments WordPress plugin, affecting versions <= 3.12.27. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.12.28; sites on affected versions should update now. Disclosed September 2026, reported by Ryoma Nishioka.

Vulnerability Overview

The Easy Appointments plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.12.27 via the handle_customers_ajax. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the full customer dataset from the ea_customers table, including personally identifiable information such as names, email addresses, mobile numbers, dates of birth, and physical addresses.

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.

CWE-862: Missing Authorization

Reaching this weakness in Easy Appointments <= 3.12.27 takes an account at Contributor level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Easy Appointments the fix is 3.12.28: builds <= 3.12.27 are affected, anything from 3.12.28 onward is not.

Remediation

Update to version 3.12.28, 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: Easy Appointments 3.12.28 closes this, and updating the plugin is the step that ends it.
