At a glance

CVE-2022-38104 is a medium-severity Missing Authorization vulnerability in the Accordion WordPress plugin, affecting versions <= 2.0.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account. The issue is fixed in version 2.1.0; sites on affected versions should update now. Disclosed September 2022, reported by R3N0.

Vulnerability Overview

The Accordions plugin for WordPress is vulnerable to arbitrary options update in versions up to, and including, 2.0.3. This is due to insufficient capability checking on the manual_import_json() function. This makes it possible for authenticated attackers to modify arbitrary options on the site and can be used for complete site takeover. This is due to an incomplete fix of CVE-2022-33198.

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

Accordion <= 2.0.3 carries this weakness at manual_import_json(), and reaching it takes any authenticated account. 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 Accordion the fix is 2.1.0: builds <= 2.0.3 are affected, anything from 2.1.0 onward is not.

Remediation

Update to version 2.1.0, 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: Accordion 2.1.0 closes this, and updating the plugin is the step that ends it.
