Vulnerability Overview
The Conditional Fields for Contact Form 7 plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check when showing admin notices in all versions up to 2.4.0 (inclusive). This makes it possible for attackers to read admin notices.
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 Conditional Fields for Contact Form 7 <= 2.4.0 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 Conditional Fields for Contact Form 7 the fix is 2.4.1: builds <= 2.4.0 are affected, anything from 2.4.1 onward is not.
Remediation
Update to version 2.4.1, 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: Conditional Fields for Contact Form 7 2.4.1 closes this, and updating the plugin is the step that ends it.
