Vulnerability Overview

The VS Contact Form plugin for WordPress is vulnerable to CAPTCHA Bypass in versions up to, and including, 14.7. This makes it possible for unauthenticated attackers to bypass the Captcha Verification.

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 privileges on the target site, and no interaction from a victim user.

CWE-804: Guessable CAPTCHA

The product uses a CAPTCHA challenge, but the challenge can be guessed or automatically recognized by a non-human actor.

Remediation

Update to version 14.8, 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: VS Contact Form 14.8 closes this, and updating the plugin is the step that ends it.
