Vulnerability Overview

The Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.4.0 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to perform an unauthorized action.

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 Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) <= 3.4.0 takes an account at Contributor 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 Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) the fix is 3.4.1: builds <= 3.4.0 are affected, anything from 3.4.1 onward is not.

Remediation

Update to version 3.4.1, 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: Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) 3.4.1 closes this, and updating the plugin is the step that ends it.
