At a glance

CVE-2023-6963 is a medium-severity Guessable CAPTCHA vulnerability in the Getwid WordPress plugin, affecting versions <= 2.0.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The Getwid – Gutenberg Blocks plugin for WordPress is vulnerable to CAPTCHA Bypass in versions up to, and including, 2.0.4. This makes it possible for unauthenticated attackers to bypass the Captcha Verification of the Contact Form block by omitting 'g-recaptcha-response' from the 'data' array.

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 2.0.5, 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: Getwid 2.0.5 closes this, and updating the plugin is the step that ends it.
