At a glance

CVE-2026-6803 is a medium-severity Missing Authorization vulnerability in the AI Copilot WordPress plugin, affecting versions <= 1.4.12. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.5.4; sites on affected versions should update now. Disclosed July 2026, reported by Kazuma Matsumoto.

Vulnerability Overview

The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.4.12. This is due to missing capability checks and nonce verification on AJAX actions registered under both wp_ajax_ and wp_ajax_nopriv_ hooks, as the base controller's getPermissions() returns an empty array and neither removeGroup nor clear are added to getNoncedMethods(), causing the authorization gate to unconditionally return true for these actions. This makes it possible for unauthenticated attackers to delete specific records by ID or delete all records from any module's database table by unauthenticated attackers.

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 privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

AI Copilot <= 1.4.12 carries this weakness at getPermissions(), and reaching it takes no account at all. 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 AI Copilot the fix is 1.5.4: builds <= 1.4.12 are affected, anything from 1.5.4 onward is not.

Remediation

Update to version 1.5.4, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: AI Copilot 1.5.4 closes this, and updating the plugin is the step that ends it.
