At a glance

CVE-2026-9015 is a medium-severity Missing Authorization vulnerability in the Equalize Digital Accessibility Checker WordPress plugin, affecting versions <= 1.42.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.42.1; sites on affected versions should update now. Disclosed May 2026, reported by w1zard.

Vulnerability Overview

The Equalize Digital Accessibility Checker – WCAG, ADA, EAA and Section 508 compliance plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.42.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the ignore state, ignore reason, and ignore comment of arbitrary accessibility issues across the entire site — including mass modification of all rows sharing an 'object' identifier when largeBatch=true is supplied — corrupting accessibility audit integrity by hiding or dismissing findings outside their authorization scope.

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-862: Missing Authorization

Equalize Digital Accessibility Checker <= 1.42.0 carries this weakness at object, and reaching it takes an account at Subscriber 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 Equalize Digital Accessibility Checker the fix is 1.42.1: builds <= 1.42.0 are affected, anything from 1.42.1 onward is not.

Remediation

Update to version 1.42.1, 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: Equalize Digital Accessibility Checker 1.42.1 closes this, and updating the plugin is the step that ends it.
