Vulnerability Overview

The Design for Contact Form 7 Style WordPress Plugin – CF7 WOW Styler plugin for WordPress is vulnerable to unauthorized access due to missing capability checks on several functions in versions up to, and including, 1.6.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform several unauthorized actions.

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

Reaching this weakness in WOW Styler for CF7 <= 1.6.4 takes a caller who can reach the endpoint. 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 WOW Styler for CF7 the fix is 1.6.5: builds <= 1.6.4 are affected, anything from 1.6.5 onward is not.

Remediation

Update to version 1.6.5, 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: WOW Styler for CF7 1.6.5 closes this, and updating the plugin is the step that ends it.
