reCAPTCHA v3 - Critical - Access bypass - SA-CONTRIB-2020-019

Project: reCAPTCHA v3
Date: 2020-May-13
Security risk: Critical 18∕25 
Vulnerability: Access bypass

Description

The reCaptcha v3 module enables you to protect your forms using the Google reCaptcha V3.

If the reCaptcha v3 challenge succeeds, all the other form validations are bypassed. This makes it possible for attackers to submit invalid or incomplete forms.

This vulnerability only affects forms that are protected by reCaptcha v3 and have server side validation steps (e.g required field or custom validation functions).

Solution

Install the latest version:

If you use the reCAPTCHA v3 module for Drupal 8.x, upgrade to reCAPTCHA v3 8.x-1.2
Also see the reCAPTCHA v3 project page.
