Vulnerability Overview

The Contact Form 7 – Dynamic Text Extension plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the CF7_get_custom_field and CF7_get_current_user shortcodes due to missing validation on a user controlled key. This makes it possible for authenticated attackers with contributor access or higher to access arbitrary metadata of any post type, referencing the post by id and the meta by key.

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-359: Exposure of Private Personal Information to an Unauthorized Actor

The product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected.

Remediation

Update to version 4.2.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: DTX 4.2.0 closes this, and updating the plugin is the step that ends it.
