At a glance

CVE-2026-14196 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the WCFM Marketplace WordPress plugin, affecting versions <= 3.8.0. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Store vendor level or above. The issue is fixed in version 3.8.1; sites on affected versions should update now. Disclosed August 2026, reported by Mustafa Ahmed.

Vulnerability Overview

The WCFM Marketplace plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.8.0. This is due to missing ownership verification on the reviewid parameter in review status update and deletion functions. This makes it possible for authenticated attackers to delete or update the status of reviews belonging to other vendors by manipulating the review ID.

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-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in WCFM Marketplace <= 3.8.0 takes an account at Store vendor level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For WCFM Marketplace the fix is 3.8.1: builds <= 3.8.0 are affected, anything from 3.8.1 onward is not.

Remediation

Update to version 3.8.1, 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: WCFM Marketplace 3.8.1 closes this, and updating the plugin is the step that ends it.
